Travis CI: Continuous Integration for PHP Project


Introduction:


While the last article was “Get Started With Test Driven Development: Unit Testing With PHPUnit?. ”, this article will help to getting started with Travis, which make collaboration with your team breeze.

Travis CI is an automation tool which allows team to commit and build project easily. Once you have configured your GITHUB project, whenever there is a new commit, Travis CI will sync code from GITHUB repository and initialize the build process. This way developer don't need to worry about running PHPUnit every time. Travis builds & deploy your software rapidly. I personally like Travis CI as an automation tool because it is easy to integrate, clean UI, plenty of features whereas getting started with other automation tool little tricky.

Travis CI supports multiple programming languages, you just need to define in your .travis.yml file (in root directory of the project) that which language project written and remaining Travis will take care. I will not be able to explain all language and environment they support, you can find from their documentation. In this article we will focus on “How to integrate Travis CI (continuous integration) tool with PHP project on GITHUB repository.”

Get Started With Travis CI:

Below are neat steps for Integrating Travis CI in your GITHUB projects.

Step1: Travis UI- Sign in:

Sign in into Travis CI Tool using your GITHUB account.


Step2: Travis Setup- Activating for the repository:

Setting up Travis is very simple and straight forward. Once you logged into Travis, go to profile page and you can see your entire GITHUB repositories already synchronized and displaying into the page. Choose which repository you want to build, activate/deactivate it using simple “on”/“off” button as below screenshot.


If you have created a new repository into GITHUB under the same account and it is not displaying into Travis profile page, then simply click on “Sync” button as highlighted in above screenshot. Once you activate Travis for your repository every time you commit into the repository Travis will trigger build process.

Step3: Travis Aware- Add a .travis.yml file into your Repository

Different project will different environment setup. To inform Travis CI under what environment you require to build and test your project, you need to add a configuration file named .travis.yml in root directory of your GITHUB project. Below sample example,


Above .travis.yml configuration file informs Travis that it is PHP based project, Travis should run tests against 4 different versions of PHP as well as in HVVM. It also tells that project will accept failure in PHP v7.0, before build it should update the composer version. It will run all our tests suits located into tests directory.

By default on every Build Failure Travis will notify you via email. However you can stop notification by changing the notification flag as "false" as above screenshot.

To verify yml config file use http://lint.travis-ci.org/.

A great way to learn about .travis.yml is browse through various open source projects in GITHUB repositories that are uses Travis CI for build process. Here some example below,

Step4: Adding Travis CI Service into GITHUB:

Goto your Travis profile page by clicking Account, find token left hand side. This token will be used to identify your github project by Travis CI. See screenshot below,


Copy the token and while adding a service paste into the box, goto your repository settings, under “Webhooks & Services”. sample screenshot below to find location.


Step5: Travis Build- Triggering Build Process:

Now Travis is ready to build our awesome project, every time we push into GITHUB repository Travis will start building the project. You can see the build process or status in your travis page, under your githubu-username/repository-name. For example below.

https://travis-ci.org/cygnite/framework

See the build status on same page. You can see below screenshot as all tests passes for Cygnite it shows green, else it will display as red.


You can manually restart the build by clicking a button as above screenshot.

Build History:

Click on Build history tab to see history of builds it processed. Sample screenshot below.


Learn More:

You can find more information about Travis configuration in their official documentation. Some useful links below,

Wrapping Up:

I believe I gave you very good introduction of Travis CI Integration with GITHUB projects. It is really very easy to use. As popular dependency manager composer for PHP, Travis CI is also becoming favorite Continuous Integration tool for developers. So now it’s your turn, give it a try. You will be up and running fast.

Get Started With Test Driven Development: Unit Testing With PHPUnit?



Introduction

While last article was "10 Best PHP Tools For Developers", choosing better tools for web development, this article is for those who want to write better testable code.

You might have come across such situations where you write bunch of code as library or component, where one library is depend on another, and when you fix one bug another comes up. This is frustrating when you need to go for production deployment and at the last moment you are identifying an bug which is related to your earlier fix or may be new one. You may need to sit back and debug entire application to find out where exactly going wrong. It happens for most of the developers, when we are most confident about our code, don't do unit testing or miss small piece of code which break down the application at end.

Well!! Is there any better way of delivering quality code? Yes!! Unit testing is the right approach. In this tutorial we will see how to make use of PHPUnit to develop error free application. This article is absolutely for beginner, as it will show you how to setup environment, write basic test cases using PHPUnit. You can start from here, do unit test in your future work.

Unit Testing & Why?

Before getting started with PHPunit to write some tests, let us find out "What is unit testing?", Why it required? How to get started with?

Unit testing is practice of testing unit of code or functions. By this way we can verify our code returns expected output.

From my personal experience, I would say if unit testing is in your mind, it helps you to write better testable code, refactoring existing code, helps you to build decoupled application. Consider you have been writing huge libraries for your project, due to time constraints you have skipped unit testing on the code, later on when you want to write some unit tests you couldn't, because code is not easy to test. And you will end up refactoring to write testable code. By this way unit testing helps to write testable code. It's always better to go for test driven approach, write code and keep unit testing in mind, do run tests after every changes in code, it will save you at end.

You may be wondering, If Unit Testing is de-facto standard then “Why People don't write Unit Tests?”. May be there are several reason,

• Most of the developers are confident about their code, they feel unit testing not required. But in real time some scenarios, it fails.

• It really takes lot time to test each class.

• Some people feel boring to write test assertions on every functions.

But believe me unit testing will save your ass at end and help you to deliver quality code.

Installing PHPUnit:

I will not go in detail as it is already explained in PHPUnit’s beautiful documentation. If you are using linux you can install PHPUnit using simple commands as below,


$ wget https://phar.phpunit.de/phpunit.phar
$ chmod +x phpunit.phar
$ sudo mv phpunit.phar /usr/local/bin/phpunit
$ phpunit --version

Above command will install PHPUnit globally.

PHPUnit - Composer Installation:

You can also install PHPUnit using composer, which is handy too. Just specify requirement into your composer.json as below,


{
"require": {
        "php": ">=5.4",
        "cygnite/framework": "dev-master",
   }, 
   "require-dev": {
       "mockery/mockery": "~0.9.1",
       "phpunit/phpunit": "4.8.*"
   },
}

See also: Cygnite composer.json

I hope you have composer installed already. Now go to terminal and enter "composer install" from the root directory of your project. Alternatively you can also install PHPunit globally using composer as below,


composer global require "phpunit/phpunit=4.8.*"

You can find vendor folder with PHPUnit libraries, and other packages.

Environment Setup:

In order to test the code we need some libraries. We have already installed Cygnite PHP Framework. For sample example we will test Cygnite's IoC Container class. You can define your configuration into the file phpunit.xml and the bootstrap file index.php or phpunit.php into your root directory.

Your phpunit.xml should look somewhat like below,

See also: Cygnite phpunit.xml

<?xml version="1.0" encoding="UTF-8"?>
<phpunit backupGlobals="false"
         backupStaticAttributes="false"
         bootstrap="phpunit.php"
         colors="true"
         convertErrorsToExceptions="true"
         convertNoticesToExceptions="true"
         convertWarningsToExceptions="true"
         processIsolation="false"
         stopOnFailure="false"
         syntaxCheck="false"
>
    <testsuites>
        <testsuite name="Cygnite Test Suite">
            <directory>./tests/</directory>
        </testsuite>
    </testsuites>

    <filter>
        <whitelist addUncoveredFilesFromWhitelist="false">
            <directory suffix=".php">src</directory>
            <exclude>
                <directory suffix=".php">vendor</directory>
            </exclude>
        </whitelist>
    </filter>
</phpunit>


And bootstrap file phpunit.php :

See also: Cygnite phpunit.php

define('CF_SYSTEM',1);
require __DIR__.'/vendor/autoload.php';

If you look at the xml configuration you can see we have defined the test directory also other configuration such as name of bootstrap file and colors=“true”. It helps to display success or failure in green or red respectively.

You can also specify configuration by passing argument from command line. You can read from here

Sample Application Structure:

It is sample directory structure; however it depends on your application. Now our environment ready to test something awesome.

Writing Our First Test Cases:

As a part of tutorial we will test Cygnite Framework's Container class. For sample, we will write some basic assertion to test Container class. All of our tests files are located inside tests directory.

Folder Structure:

Root Directory: phpunit/

Xml Configuration File: phpunit.xml

Bootstrap File: phpunit.php

Testable Class Path: phpunit/vendor/cygnite/framework/src/Cygnite/Container/Container.php

Test Class: phpunit/vendor/cygnite/framework/tests/Cygnite/Container/ContainerTest.php

We will also use Mockery to mock object with PHPunit. Make sure every class should be suffix with string "Test", for example below sample ContainerTest.php class.


use Mockery as m;

class ContainerTest extends PHPUnit_Framework_TestCase
{
    private $container;

    public function setUp()
    {
        $this->container = new \Cygnite\Container\Container();
    }

    public function testMakeClass()
    {
        $router = new \Cygnite\Base\Router\Router();
        $url = new \Cygnite\Common\UrlManager\Url($router);

        $madeUrl = $this->container->make('\Cygnite\Common\UrlManager\Url');
        $this->assertEquals($url, $madeUrl);
        $this->assertInstanceOf('\Cygnite\Container\Container', $this->container);
    }

    public function testClouserResolutionAsObject()
    {
        $this->container->name = function() {
             return 'Cygnite';
        };

        $this->assertEquals('Cygnite', $this->container->name);
    }

    public function testArrayAccess()
    {
        $this->container['greet'] = 'Hello World!!';
        $this->assertEquals("Hello World!!", $this->container['greet']);
    }

    /**
     * @expectedException     \Cygnite\Exception\Http\HttpException
     * @expectedExceptionMessage Not Found!
     */
    public function testException()
    {
        throw new \Cygnite\Exception\Http\HttpException(404, "Not Found!");
    }


    public function tearDown()
    {
        m::close();
    }
}


See also: ContainerTest.php

In the above example, you can see method “setUp” and “tearDown” similar as magic method __construct and __destruct, setUp is where you can do some configuration before executing test methods. For example you want to test database queries or you don’t want to create an object of class every time in all methods. In such cases, you can configure connection or create an instance of class one time into setUp() method and use it in any method of that test class. Similarly you can see, I have used tearDown() method to close Mockery object.

Few Basic Assetion Methods To Remember:

setUp() – setting up configurations etc.

tearDown() – Close connection or destroy mock objects

assertEquals – Check equality of output

assertTrue – Check method returning true or not.

assertEmpty – Check function or any argument value is empty

assetInstanceOf- Check given string is instance of specific class

assertNull – Check if value is null or not

Apart from that there are many assertion methods, you can make use of those based on the requirement. Find out those assertion functions from PHPUnit documentation. You can also use annotation for running assertion. For example you want to do some test to verify if method throws correct exceptions with exception message. Such case simply use annotation as below,


   /**
     * @expectedException  \Cygnite\Exception\Http\HttpException
     * @expectedExceptionMessage Not Found!
     */
    public function testException()
    {
        throw new \Cygnite\Exception\Http\HttpException(404, "Not Found!");
    }


In above testException method we are verifying if code throws “Cygnite\Exception\Http\HttpException” exception, and with the message “Not Found!”.

Likewise there are various "annotation" exists in PHPUnit to run assertions read from here.

Are you still wondering how to test code using PHPUnit ? Have a look at some sample tests, I executed on Cygnite PHP Framework core classes.

Running Tests:

Running tests is just simple using phpunit executable file, but you need to make sure you are pointing it to your test file. Here example:



phpunit\vendor\bin> phpunit –c ../../phpunit.xml --bootstrap ../../phpunit.php ../cygnite/framework/tests/Cygnite/Container/ContainerTest.php

// -c – Xml configuration file

// --bootstrap – Your bootstrap file to autoload all files or for some initial configurations etc.


Sample Output:

Assertion Failure:

Assertion Success:

PHPunit displays number of assertion, pass, failure, number of tests etc. If any of the tests fails it will display failed in red with method name, reason etc. And on success it will display green with number of assertion, tests etc.

Is it not easy?

Conclusion:

Though there are multiple things to cover, I believe I have given you good introduction of PHPUnit and How to write basic unit tests using PHPUnit.

So, why to be lazy? when you can deliver quality code. Start doing assertions tests on your code for current or future projects. Jump start from here with test driven development. Write code better, testable, modular. I hope this article is useful to you. Please don't forget to share with your friends and leave your comments below.

Backbone JS vs Angular JS- Uncovering key differences


Introduction

Our last article was about 8 Brilliant Tools That Empower Web Developers To Work With A Flair

Every since JavaScript development gained traction, the war of front-end JavaScript frameworks hasn't ceased to exist. As a JavaScript developer, I've tried hands on numerous JavaScript frameworks that have some of the finest features, helping in improving the overall productivity. Two of the best JavaScript frameworks that have proved utmost useful in building stunning web apps are BackboneJS and AngularJS. Today, in my post, I'd be taking up a simple and crisp comparison between these two JavaScript frameworks that have been embraced by JavaScript developers, both amateurs and experts.

BackboneJS vs AngularJS – Background

While BackboneJS is a 2010 product, AngularJS was released in the year 2009. Serving as a quick alternative to heavy frameworks, Backbone.js is a light weighted JavaScript framework that loads faster due to use of the Underscrore.js dependency framework. On the contrary, AngularJS is an open source framework that allows an easy extension of HTML in addition to two-way data binding via simple code testing. That means, with the two-way binding, you can use HTML for declaring the template, eliminating the need for writing any code.

BackboneJS vs AngularJS- Website Categories

While Backbone.js serves as an excellent choice for building eye-catchy websites for real estate, shopping, business & industry, arts & entertainment etc; AngularJS has been designed keeping in mind the need for building websites related to Career & Education, Internet & Telecom, Software, Computer & Electronics and many more.

BackboneJS vs AngularJS- Architecture

While the Backbone.js framework uses MVP(Model View Presenter) architecture, AngularJS uses the traditional MVC(Model View Controller) architecture. The main differences arising out of this variation in architecture include the following:

  • DOM -

    Unlike AngularJS which rebuilds the DOM in accordance to the specified rules, BackboneJS manipulates direct DOM for representing the changes made to the data.

  • Data Binding -

    Unlike AngularJS which comes with a two-way binding feature that allows it to run the applications, track and trigger data changes; BackboneJS lacks a data binding feature forcing the developer to create a custom binding mechanism or opt for a third-party data binding service.

BackboneJS vs AngularJS- Templating

Talking about templating, well it is in effective technique of reducing the amount of code that needs to be written for getting the single-page applications off the ground. While on one hand, we have BackboneJS which builds off the Underscore templates i.e. you're expected to write certain custom JavaScript for ensuring smooth functioning of the templates, on the other hand there is AngularJS which offers templating via dynamic HTML attributes that have already been incorporated into the document, ensuring the representation is concise and easy-to-grasp.

BackboneJS vs AngularJS- Validation

BackboneJS doesn't comprise of a function that can execute the validations part. That means, you're either supposed to write the logic by yourself or choose one from Backbone validations(9.5 unminified) or Backbone.validation(8.2HB minified) or Backbone.validator(8.2 non-minified) etc. In contrast to this, there is AngularJS which includes validation by default. That means, you can see some of the validations like min-length, max-length, email etc. implemented by default. Moreover, if you're interested in having a custom validation(s), then you can choose to create one.

BackboneJS vs AngularJS- Non-Restful Backend

While BackboneJS is purely meant for Restful backends, AngularJS comes with $http which allows you to go beyond the boundaries of a Restful backend. Well, when it's about Backbone.JS, for each end-point within the backend, there's a need for creating an associated model on the front-end. That means, if you aren't using a Restful backend, then there will be a need for performing a lot of tweaks that may lead to multiple overrides to Backbone.sync. On the contrary, AngularJS makes the concept of having a Restful backend easier. It comes with ngResource- an extra file that's required for adding 16KB min. Hence, you're free to either use this file or $http directly.

BackboneJS vs AngularJS- Overall Performance

In simple words, BackboneJS is a lot more faster and better performing as compared to AngularJS. The basic reason for this is that as the page grows, AngularJS's two-way data binding feature tends to introduce negative performance effects into the framework. Unlike this, BackboneJS lacks a data binding feature, expecting you to write lengthy code. This allows you to focus on improving the performance, removing the need for hacking the framework from scratch. All in all, it is the compact data representation which makes AngularJS a low-performing JavaScript framework.

Final Thoughts

While each of the two JavaScript frameworks viz: BackboneJS and AgularJS have their own set of pros and cons, it is better to opt for the one which suits your project requirements fully. Remember, a framework that's been chosen after a lot of planning and analysis will fetch you the desired results instantly.

This post will unleash a few worthy benefits of AngularJS.

1. Has an ideal framework size that helps develop a variety of apps

The most common cause that add to the bounce rate of a product is its loading time. If your application consumes a lot of time to load, most of your users will certainly prefer abandoning your app. Thus, it is better to scour the impact of a framework on the loading time. This can be proficiently analyzed by taking the framework size and time taken by the framework for bootstrapping into account. AngularJS consumes ~50 KB, and allows professionals to develop beautiful, feature rich applications with a flair.

Unerring Tips for High Performing WordPress Themes


Introduction:

In the last article we discussed about "Advantages and Disadvantages of Ecommerce Business".

“Doing The Same Thing Over And Over Again And Expecting Different Results”

This is what we call insanity. If you think that you are doing everything right but the desired result is still awaited, then you need to go back, test and then optimize your policies. We all have been ranting and raving about responsive themes, but we never dared to look beyond it. In this blog, we will discuss how to get high performance from your WordPress themes.

Gauging the performance of your Responsive theme

Choosing the size of a responsive web theme matters because it affects the end users as well as the web servers. Due to heavy weightage, server needs more time to get extra file and with each such file, extra milliseconds are added in the loading time. On the other hand the user have to wait till the total number of kilobytes are loaded. Apart from using Media Queries various WordPress themes now use several other techniques to respond to the browser's.

Being choosy pays off!

Designing a responsive website is more than just defining different number of columns in a website. This question was for all the websites designed for mobile users, without concerning the fact that these were CMS. Before choosing a theme you need to first go through the following set of questions:

Does your project needs a mobile development?

With the proliferation in the mobile devices it is highly unlikely for business owners with up to date market knowledge and trends to say no to mobile first technology. However, one cannot go on for adopting all kind of technological development. Though, earlier we had a choice for adopting mobile designs, but now with the advent of Google's algorithm it becomes crucial.

Read: Creating ​Mobile ​Responsive ​Design

How many steps do we need?

Performance of a responsive website depends highly on the screen it is viewed on. Responsive design does not mean that the screen should adjust on the mobile devices such as tablet, phablet or smartphones, wherein responsive means that your website must be fit to wide screen sizes. The best option is follow device-agnostic approach which focuses on web design instead of device functionalities.

Do you understand the layout and formatting of the responsive pages?

In order to craft a successful layout you need to display the elements one by one. Now, when it comes to wide screens we must make sure that the headings must be larger than the content, whereas when it comes to smaller screen the ratio drastically changes.

How to tailor your application for mobile devices?

Displaying content via multiple columns needs a particular hierarchical flow, as each page comprises of its own unique content and secondary content is the one which is displayed on more than one page. This content approach is difficult to follow while designing for mobile screen. You need to ensure that you need to remove the irrelevant content from the mobile screens. On contrary if you think that you need all those pages then draw out a proper methodology such as long scrolling to display you content. Further, as per thumb rule the elements which do not supports the title of the page is not the primary content.

Measure your Websites performance

Now after all the detailed analysis and study you have finally chosen a WordPress theme and have decided on the content placement and stuff, do not think that you have accomplished your goal. The next step is to know whether you did it right and is your website well accepted by users. There are numerous tools present in the market to gauge the performance of a website. However, you can count on Google Page Speed and for second choice keep Gtmetrix for analyzing the current performance of your website.

Read: 5 Best Things You Should Know About PHP 7

With 7 Google Page rank and Alexa rank 11, Gtmetix serves as an incredible tool for analyzing your website. Along with page speed results this tool uses YSlow ( a tool from Yahoo for measuring performance). Do not worry as you do not have to do much and all you need to do is to enter the url of your website to get a comprehensive performance report. Further, it allows comparative analysis for a healthy competition.

Poor performance!

Plugins can ameliorate the performance

One can certainly meter the performance of their website, however this leads to the crux: how to improve?

With a wholesome development of community existing for more than a decade have found solution of this unnerving questions. We have plugins namely auto optimize, WP Super Cache and several other which can work as a performance booster for your WordPress website. These plugins are easy to install and ready to use which have the potential to ameliorate the performance of a poor performing websites.

Present the cached version

Caching works as a performance booster!

As we know that every time a user enters a website, content is fetched from the server and then displayed on the browser. In case of static resources the data will fetched every single time a user visits the website. This is certainly not an optimal technique, as the server has to do a single task over and over again.

In order to optimize this functionality we have well engineered plugins such as WP Super Cache, which ensures that the users get to access the cached website which removes the unnecessary loading of content again and again.

I hope this might help you!

Conclusion:

The long and short of the complete article is that we need to pull up our socks in order to do reach another level of web development. There are a lot of optimization techniques for WordPress which one can harness to provide top notch solutions.

How to Guide to Create ​Mobile ​Responsive ​Design


Introduction:

Hey Guys! Last article was about "How to Install Ubuntu 15.04 Along With Windows 8 (Dual Boot)".

Unlike a conventional desktop oriented website, the one which has been created for the mobile screens is a lot more in demand. It is a responsive website which automatically adjusts itself to fit the screen of device that the site is being viewed on. All the content, whether it is the text, images or video get moderated to ensure best display on the screen under focus. Whether you're a publisher, a designer or a developer, taking care of your site's mobile responsive design is something that can render flawless experience to the targeted users. In this post, I'll be walking you through the vital steps that must be followed for building a fine quality mobile responsive design.

What kind of mobile responsive design are we going to create in this tutorial?

Here, I'll be creating a simple e-commerce product detail page for a t-shirt firm. So, while ensuring that the customers are able to make the purchases conveniently, we'll also be making the product review easy-to-access, followed by utilizing customer's location for enhancing the overall mobile shopping experience.

A look at the basic structure

It is essential to author a semantic HTML5 markup that will allow you to ensure completely manageable and fully accessible adaptive experiences. The reason for this being that semantic markup is fully portable and can be easily accessed on a variety of mobile devices, desktop browsers, tablets etc.

Coming to the individual steps for creating mobile responsive design

Step 1- Set the Viewport

While for a majority of non-mobile-optimized websites, most of the contemporary browsers set up a larger browser viewport, in case of designing a website using mobile responsive design, we'll be using viewport meta tag for setting the screen width to the device width as shown below:


<meta name="viewport" content="width=device-width, initial-scale=1" />

Step 2- Adding the flexibility to load the website content conditionally

Here, we'll be creating two new HTML documents for the auxiliary content viz: reviews.html and related.html. Unlike the default way in which the content is accessible via links available on the page, we can use a little bit of javascript for loading the content as and when user requests for the same or when the screen's resolution reaches a specific breakpoint.

Step 3- Use HTML special characters

As an attempt to decrease the need for background images, it is recommended to use HTML special characters. In this tutorial, I've used $#9733 for creating a solid star (★) and ☆ for creating empty stars (☆) for the product ratings.

Step 4- Include a clickable link within footer

Here, we'll use the tel URI scheme for including a clickable link to customer service number, within the footer. Here's a look at the tel URI scheme:


<a href="tel:1234567891">123 456 7891</a>

Step 5- Add style enhancements

With a strong semantic markup in place, it's time to add some style enhancements as explained below:

Create separate style sheet for screens with larger displays

Here, we'll be creating two CSS files viz: style.css and enhanced.css for delivering basic styles for screens with dimension less than 967px. We'll be using media queries for serving the new styles for screens with dimension greater than 967px as shown below:


<link rel="stylesheet" href="style.css" type="text/css" media="screen" />
<link rel="stylesheet" href="style-967.css" type="text/css" media="screen  and (min-width: 967px)" />
<!--[if (lt IE 9)&(!IEMobile)]>
<link rel="stylesheet" href="ie9.css" type="text/css" />
<![endif]-->

Adding Mobile-first styles

Next, we can start off with adding shared styles and advanced layout rules as shown below:



/* Avoid this style */
.customer-list img {
  width: 30%;
  float: left;
}
@media screen and (max-width: 967px) {
  .customer-list img{
    width: auto;
    float: none;
  }
}


The mobile-first approach will now look like this:



@media screen and (min-width: 967px) {
.customer-list img {
    width: 30%;
    float: left;
  }
}


Next, we'll be applying media queries as shown in the below code snippet:


/*Display 2 per row for medium displays*/
@media screen and (min-width: 480px) {
  . customer-list li {
    width: 50%;
    float: left;
  }
}
/*Display 3 to a row for large displays*/
@media screen and min-width: 768px) {
  . customer-list li {
    width: 33.33%;
    float: left;
  }
}



Step 6- Use CSS for reducing HTTP requests

Have a look at the below CSS which will play a vital role in saving HTTP requests so as to improve the overall performance of your website. For instance, CSS gradients can replace background images for decreasing the count of image requests and rendering a greater control over the original design.



/*Using CSS gradients rather than background images*/
header {
  background: #333; 
  background: +linear-gradient (top, # 333 0%, #555 100%);
}


Step 7- Add Javascript enhancements

To start off, we'll be adding functionality to the site's navigation. In the HTML5 Markup, we'll using a list #top-menu for toggling the visibility of navigation as well as the search bar on all small screens. Have a look at this:


<ul  id="top-menu" class="top-menu">
  <li><a href="#">Menu</a></li>
  <li><a href="#">Search</a></li>
</ul>
<nav id="main-menu" class=" main-menu">
  <ul role="main-menu">
    <li><a href="#">Home</a></li>
    <li><a href="#">About</a></li>
    <li><a href="#">Services</a></li>
  </ul>
</nav>


Additionally, we will include a resize listener which will find whether there's any possibility of displaying the search bar and navigation. Have a look at this:



var swidth, sheight ;
$(window).resize(function(){
  swidth = document.documentElement.clientWidth;
  sheight = document.documentElement.clientHeight;
  setElements();
});
  
//Set elements according to differ screen size
function setElements() {
  device = (swidth < breakpoint) ? true : false;
  if (!device) { 
    $('#top-menu').show(); 
  } else {
      $('#top-menu').hide();
  }
}


Adding functionality to the Image Gallery

To start off, we'll be adding functionality to the site's navigation. In the HTML5 Markup, we'll using a list #top-menu for toggling the visibility of navigation as well as the search bar on all small screens. Have a look at this:

Have a look at the below code snippet which will allow us to build an image carousel using the available thumbnail images:



function intslide() {
  container.html('<div id="img-slider"><ul /></div>');
  imgSlider = $('#img-slider');
  $('nav a:first-child').addClass('active');
  
  $('nav a').each(function() {
    var href = $(this).attr('href');
    imglist += '<li data-src="'+href+'"></li>';
  });
  
  imgSlider.find('ul').append(imglist);
      
  $('nav a').on('click', function(e) {
    var slidepos = $(this).parent().index();
    e.preventDefault();
    loadImg(slidepos);
    if(swipeEnabled) {
      mySwipe.slide(index, 500);
    }
    updateNav(slidepos);
  });
}



Adding functionality for Related Content

A code snippet will allow us to pull in related content in case any one of the below two conditions are met:

 When a mobile user clicks on related t-shirts or the product reviews links

 When screen has enough space for loading the auxiliary content

The code snippet that I'm referring to is shown below:



function setElements() {
    device = (swidth < breakpoint) ? true : false;
  
  if (!device) {
    loadContent(); 
  }
}

//Set up content
function loadContent() {
  var $content = $('.content');
  $content.each(function(index) {
    var $this = $(this);
    var contentLink = $this.find('a');
    var contentFragment = contentLink.attr('href');
    var realContent = $this.find('.demo');
    if (realContent .size()===0 && $this.hasClass('loaded')===false) {
      getContent(contentFragment,$this);
    }
  });
}

function getContent(src,container) {
  container.addClass('showcontent');
  $('<div class=”demo” />').load(src +' #content > div',function() {
    $(this).appendTo(container);
  });
}


As an approach to keep the web pages lightweight, I recommend using Closure Compiler for chopping off all the unused bits of the jQuery library. Other impressive alternatives include popular micro-frameworks like Zepto.js etc. Finally, don't forget to pay special attention to ensuring seamless off line access to your website. This will serve as a brilliant surprise to mobile users who aren't connected to the Internet at times.

We're done!

Conclusion:

With that it's a wrap on this post which made you familiar with the basic steps of creating a mobile responsive design. Hope by having a responsive design, it will become convenient for you to adapt to all the future mobile devices and browsers quite conveniently and instantly.

How to Install Ubuntu 15.04 Along With Windows 8 (Dual Boot)


Introduction:

Hey Guys!

In my last article shown you How to install LAMP stack with easy steps. Today I would like to write about “How to install Ubuntu 15.04 along with Windows 8”. Recently I was trying to make my system dual boot (Ubuntu 15.04 alongside Windows 8), I have faced couple of issue before I am successful. It is not anymore that easy to install Ubuntu 14.10/ 15.04 alongside Windows 8, earlier we were able to install directly using WUBI installer. I thought I can post steps here, so that it will also help others. If you have Windows 8 pre-installed, you may find difficult to install Ubuntu or any other OS alongside. Microsoft has introduced several new features which made a mess for Linux based operating system. Windows 8 introduced UEFI and secure booting which is preventing any other operating system to install. UEFI is basically similar as BIOS booting.

You should know that until UEFI mode and secure booting is enabled you cannot directly boot/use Ubuntu. Installing Ubuntu inside Windows using WUBI is not supported in Windows 8.

Here I am posting some steps as I followed towards successful Ubuntu installation alongside Windows 8.

You might also be interested on reading “Installing LAMP stack on Ubuntu 15.04”

Step 1: Download Ubuntu ISO File

Download Ubuntu from the website. Make sure you are downloading 64 bit, 32 bit may not work. In my case I have downloaded 64 bit version.

Step 2: Use Universal Installer to Install Ubuntu

Make sure you have space least 10 GB in separate drive. In my case I have created a drive with 100GB for Ubuntu installation. Burn the Ubuntu into Live CD, DVD or USB in windows. I have used USB drive to boot Ubuntu. Download USB installer and install it. Browse downloaded Ubuntu ISO as below screenshot below.

Choose USB drive and click create to install Ubuntu into your USB drive.

Step 3: Disable Fast Startup (Windows 8 or 8+)

This technique introduced in Windows 8 to reduce booting time. When we shut down our Windows 8 system, it use hibernate concept to write some system data from RAM to disk. Doing this when next time windows boot it restore the data faster. By this way Windows 8 manage to boot in 10 seconds on SSD. This is creating a problem for Ubuntu or any other operating system installation process.

So it’s important to disable Fast Startup in Windows 8 / 8.1 before installing Ubuntu.

Go to Power option and click on the “Choose What Power buttons do” link from left menu. You will be landed on screenshot below.


Click on the highlighted link “Change settings that are currently unavailable” to change settings and uncheck “Turn on fast startup” screenshot below.



That’s it well good to go for installation process.

Step4: Disable Secure Boot

Next important thing is to disable secure boot. You can go to boot manager from BIOS (By Pressing ESC/Delete or F1-F12 keys) setup when system starts, In my case I pressed ESC to go to “BIOS settings” from there “boot manager” in that section you also will find “Secure Boot” make sure it is disabled. Windows 8 has UEFI design which is replacement of BIOS.

Save changes and we are ready to install Ubuntu now.

Step 5: How to Install Ubuntu 15.04

Install Using USB drive

Plug in USB drive into your system and restart. When you restart system you will find screen to “Try Ubuntu” and “Install Ubuntu”. Click on “Try Ubuntu” as this helps to check your hardware compatibility. You will login into Ubuntu and see screen below.


Click “Install Ubuntu 15.04” highlighted above. This is lead you to installation process.

Select Installation Type:

On the “Installation type” screen you need to select “Something else” as we are going to make “Duel Boot” with Windows, screenshot below.


Select appropriate drive to install. Before pressing next button remember to format drive using “change” button and it should be “Ext4” file system. Mounting point should be “/” as it will install Ubuntu into that primary drive. Screenshot below.


That’s all we are done with main job, now you need to do regional, language, account settings etc. for successful installation. Wait till process completes and it will ask to restart, do restart.

First Time Ubuntu Booting:

Remove USB and after system restart, you will see screen below where you need to select Ubuntu to boot.


Boot Repair

Some time you may not see the above screen and Ubuntu may directly boot. I was facing the same issue. If you don't see screen prompting you to choose which Operating system to use “Windows 8” or “Ubuntu” you need to execute below command from Ubuntu Terminal to enable GRUB window on startup.



 sudo apt-get update
 sudo apt-get upgrade
 sudo add-apt-repository ppa:yannubuntu/boot-repair
 sudo apt-get update
 sudo apt-get install -y boot-repair && boot-repair
 

Above command will repair boot screen issue. Restart the system. You will be able to see screen where you can choose “Windows” or “Ubuntu” to boot.

Step 6:

That's all we are done. Enjoy the Linux flavor alongside Windows.

Conclusion:

Setting up Ubuntu 15.04 alongside Windows 8 for open source development is little challenging but following above steps you can easily achieve it. I faced couple of issue before successfully installation. Don’t wonder if Ubuntu installed drive is missing in Windows 8 “This PC”, it won’t display since the drive is “ext4” formatted for Ubuntu installation.

I hope this tutorial will help you. If useful please share, leave comments below. I will continue writing and try to bring some tutorial of real time challenges.

Stay Tuned! Have a nice day.

5 Best Things You Should Know About PHP 7



Introduction:

Hey Guys!

Last article was “Building A Simple Product Management App Using Angular JS + Cygnite PHP Framework + Bootstrap - Part1”.. Tutorial part2 will be posted coming days. I have drafted this article couple of days back and finally got some time post here. You might have heard about the new major version of PHP is under active development since a year and finally scheduled to release this year. The PHP 7 timeline was approved by core members and aims to release PHP7 in OCT 2015. Even though little delay but we are lucky to see PHP7 end of this year. With the RFC for PHP7 timeline passed (32 to 2). We have now entered into new generation and PHPng is almost ready to speed you up.

The features of PHP7 are fairly enough for advance web application development and making use of latest resources to boost you development. There are lot of talks about PHP5.7, PHP6 or PHP 7. The main reason behind the PHP7 is PHP6 has never reached to stable version, also there are many resources available about PHP6. So PHP community has chosen PHP5.6 to directly PHP7.

Let us get into some details.

1# Performance:

You might have heard about Facebook HVVM out there, to provide you maximum performance for PHP based application. So PHPNG (PHP-Next-Gen) started with the idea to provide maximum performance as Facebook HVVM provides. The performance improvement source was led by ZEND to speed up PHP based applications. As per Zend performance improvement is huge! You can find some benchmark against HVVM here. Without changing single piece of code, just upgrading to PHP7 gives you enormous performance. Deprecating many redundant features also part of performance improvement of PHP7.

2# Scalar Type Hints & Return Types:

While many developers would like able to declare return type for the function or method. By default PHP7 will allow developers to declare what kind of return type function is expected to return a value. It is almost similar as Type hinting parameters as below.

Example:



  public function isValidUser(int $id) : bool 
  {
     return isset($this->users[$id]) ? true : false;
  }


Above example is similar as Facebook HACK syntax. In this example bool indicates the function will return only boolean value. You can also have look at many example in RFC here.

This allows developers to set expecting strings, int, float or bool to be passed or returned.

3# Spaceship Operator

PHP7 will introduce a new operator called spaceship operator (<= >) otherwise called combined comparison operator. It can be used mostly in sorting and combined comparison. It works like strcmp() or version_compare().

As per the PHP RFC common uses of sorting as below.

Example:

Before PHP7:



  function order_func($a, $b) 
  {
    return ($a < $b) ? -1 : (($a > $b) ? 1 : 0);
  }


After PHP7:



  function order_func($a, $b) 
  {
    return $a <=> $b;
  }


It is a beautiful addition to the PHP version. You can find more example here.

4# Additional Features

Apart from above changes there are few new features added into the PHP7 core. I am listing few major changes below.

  • Abstract Syntax Tree: – Another big change on the core. But most likely to be visible to developers. It makes parsing php code easier, less error, and way to build better things in future.

  • Closure::call() : – This is the new method added into core. It allows variable binding at call time rather pre-binding.

  • Null Coalesce Operator : – The coalesce operator or ?? added to the core, which returns the first operand is exists or null.

    Example:

    Before PHP7:

    
    
        $id = isset($_GET[‘id’]) ? $_GET[‘id’] : null;  
    
    
    

    In PHP7:

    
    
        $id = $_GET[‘id’] ?? null;  //equivalent of writing old above syntax 
    
    
    
  • Uniform Variable Syntax : – The main deference of existing syntax and new syntax is to keep consistence and complete variable syntax. Allows advance expressions.

    Example:

    
    
        $$foo['bar']['baz']   interpreted as   ($$foo)['bar']['baz']
        $foo->$bar['baz']()   interpreted as   ($foo->$bar)['baz']()
    
    
    
  • Unicode Codepoint Escape Syntax: – PHP7 introduced syntax to escape unicode codepoint as below.

    Example:

    
    
        echo "\u{202E}Reversed text"; // outputs ‮Reversed text
        echo "\u{1F602}"; // outputs 😂
    
    
    

5# Cleanups:

Developers can stop recognizing method name as class name to be a constructor as per PHP4 . It has been controversial early to remove but later has been removed completely as currently we no longer required to warn PHP developer how PHP4 works. This removal added as simplicity.

mysql_* functions are completely removed as extension removed by default.

Multiple default clause support has been removed from the switch case.

Support of ASP tags (<%) and script tags (<script language="php"> </script>) has been removed meaning that you can use those tags to enter php mode.

You can find more, list of deprecated or removed functionalities here, Removed deprecated functionalities in PHP7 .

Conclusion:

Personally I believe recent changes of PHP versions, makes PHP as much more matured language. But it is good message to all PHP developers for building awesome enterprise level applications using latest PHP version.
