Getting any YouTube videos thumbnail image is quite easy. you just need a ID of particular youtube video to get it's thumbnail image in different resolutions. Use following URLs in your image tag to show required youtube thumbnail.

http://img.youtube.com/vi/<insert-youtube-video-id-here>/default.jpg -   default
http://img.youtube.com/vi/<insert-youtube-video-id-here>/mqdefault.jpg - medium 
http://img.youtube.com/vi/<insert-youtube-video-id-here>/hqdefault.jpg - high
http://img.youtube.com/vi/<insert-youtube-video-id-here>/sddefault.jpg - standard
http://img.youtube.com/vi/<insert-youtube-video-id-here>/maxresdefault.jpg  - maximum resolution

Following is a actual implementation to show how it works.

<div class="container">
  <div class="row">
    <div class="col-md-12">
       <iframe width="560" height="315" src="https://www.youtube.com/embed/RGzKJCOE5rw" frameborder="0" allowfullscreen></iframe> 
      <h1>Get different resolution of thumbnail images of Youtube video using youtube video id </h1> 
    <h1>Default image </h1>
    <img src="http://img.youtube.com/vi/RGzKJCOE5rw/default.jpg" >
    <h1>full size image </h1>
    <img src="http://img.youtube.com/vi/RGzKJCOE5rw/0.jpg" >
      <h1>Medium quality image </h1>
    <img src="http://img.youtube.com/vi/RGzKJCOE5rw/mqdefault.jpg" >
    <h1>Standard definition image </h1>
    <img src="http://img.youtube.com/vi/RGzKJCOE5rw/sddefault.jpg" >      
    <h1>High quality image </h1>
    <img src="http://img.youtube.com/vi/RGzKJCOE5rw/hqdefault.jpg" >    
    <h1>Maximum resolution image </h1>
    <img src="http://img.youtube.com/vi/RGzKJCOE5rw/maxresdefault.jpg" >

Quick fix to "www.example.com:443:0 server certificate does NOT include an ID which matches the server name" error

This problem happens more often on Windows platform, because of smaller Apache's default stack size. just find htttpd.conf file from Path_to_xampp/apache/httpd.conf and put following code

<IfModule mpm_winnt_module>
   ThreadStackSize 8888888
</IfModule>

Following code is useful when you came into scenario where you want to encrypt any data using PHP and want to decrypt it and use it via JavaScript. This can be achieved by just one line of code. It will be very basic level of encryption but very useful. Use following PHP code to encrypt any data.

<?php 
// You can encrypt any string using PHP's base64_encode function

$encryptedSting = base64_encode("your secure data");
// if you print encrypted string it will look like following sting 

echo $encryptedSting;
// Result - "eW91ciBzZWN1cmUgZGF0YQ=="
?>

In JavaScript there are two functions respectively for decoding and encoding base64 strings.

atob()
btoa()

Now once the String is encrypted, you can decrypt it by using atob() function.

<script type="text/javascript">
 // Let's say now you have encrypted sting.
 // just use atob()  function to decrypt previously encrypted data

var decryptedData  = atob("eW91ciBzZWN1cmUgZGF0YQ==");

// check you output in console
Console.log(decryptedData);

</script>

YEAH!! THAT's IT.
