missing mcrypt – Fatal Error: Undefined function mcrypt_encrypt()! in Ubuntu 13.10/14.04

I came across this problem when I upgraded my Ubuntu to 14.04. I have used php-mycrypt in one of my project which was working fine until my ubuntu got upgraded and now when I try to access my project I get this Fatal Error 
Fatal Error: Undefined function mcrypt_encrypt()
The solution looks simple but it took me ages to figure out and after a lot of googling around (most of the solution provided didn't help me at all ) so I thought I will share this hoping that you guys end up here quickly and don't have to spend much of your time (like I did ) :):) and hoping this will help you guys.

So, without wasting much of your time. Let me begin, First thing to do is see if you have installed php5-mcrypt (like everyone does), you can do that by: 
sudo apt-get install php5-mcrypt
It should install mycrypt and if already installed, you will get the following message: 
Reading package lists... Done
Building dependency tree       
Reading state information... Done
php5-mcrypt is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 13 not upgraded.
Looks good till now but wait a second, I still get that undefined fatal error. so what now,
Secondly,
see your ini file is in correct path. If not then move it (not neccessary if it is already there) 
$mv /etc/php5/conf.d/mcrypt.ini /etc/php5/mods-available/
Thirdly,
Enable mcrypt module. run the following command to enable it: 
sudo php5enmod mcrypt
Restart Apache 
sudo service apache2 restart
Try it out now And HOlA!!!!! IT works.

Hope it helped. Feel free to comment or you have any concerns or you know any other way :). Let us help each other and yes Happy coding.

jquery attr() vs prop() (difference)

according to the docs jQuery.attr() Get the value of an attribute for the first element in the set of matched elements. whereas,  jQuery.prop() Get the value of a property for the first element in the set of matched elements. Before jQuery 1.6 , the attr() method sometimes took property values into account when retrieving some attributes, which caused in inconsistent behavior. And thus, the prop() method was introduced. As of jQuery 1.6. , the .prop() method provides a way to explicitly retrieve property values, while .attr() retrieves attributes. What actually is Attributes? Attributes carry additional information about an HTML element and come in name=”value” pairs. You can set an attribute for HTML element and define it while writing the source code. simple example can be: here, "type","value", "id" are attributes of the input elements. What is Property? Property is a representation of an attribute in the HTML DOM tree. on...

Jquery 'On' (Events,Direct ,Delegated)

jQuery makes it easy to respond to user interaction with a web page. Example, this code listen to click event on all element in a document and alert the text in it. HTML click 1 click 2 JQUERY There are other methods for event binding such as click(), keydown(), keyup(), blur() and so on, all of which make use of jQuery's .on() method. jQuery's .on() method attachs an event handler function for one or more events on selected elements. The example given above is Direct event. which basically means : HEY!!!! I want every div to listen up: when you get clicked , give me alert. Here, each of these div has been individually given click event which works as it should. However  if you notice in jquery's DOC, According to the jquery's documentation: Event handlers are bound only to the currently selected elements; they must exist on the page at the time your code makes the call to .on(). so, now what if some of the div is generated dynamically...

PHP Profiling Using Xdebug and Kcachegrind

Xdebug's Profiler is a powerful tool that gives you the ability to analyze your PHP code and determine bottlenecks or generally see which parts of your code are slow and could use a speed boost. The profiler in Xdebug 2 outputs profiling information in the form of a cachegrind compatible file. This allows you to use the KCacheGrind tool (Linux,) to analyse your profiling data.  Xdebug profiler is incorporated in the Xdebug tool. Therefore you first need to download, install, and enable Xdebug itself and after that enable the profiling functionality within it. Install x-debug through apache sudo apt-get install php5-xdebug Enabling Xdebug integration with the PHP engine Once xdebug is installed, you can enable the xdebug(profiler) to work with PHP by adding following lines at the end of  php.ini  file. [xdebug]   zend_extension= "/usr/lib/php5/20121212/xdebug.so"    ;path to xdebug.so xdeb...
