GET vs POST
• Both GET and POST create an array
This array holds key/value pairs, where keys are the names of the form
controls and values are the input data from the user.
• Both GET and POST are treated as $_GET and $_POST.
These are “superglobals”, which means that they are always accessible,
regardless of scope - and you can access them from any function, class
or file without having to do anything special.
• $_GET is an array of variables passed to the current script via the URL
parameters.
• $_POST is an array of variables passed to the current script via the
HTTP POST method.

Session
• A PHP Session variable is used to store information about the user, or
change settings for a user session.
• Session variables hold information about one single user, and are
available to all pages in one application.
• session_start() Start new or resume existing session.
• session_destroy() Reset your session and you will lose all your stored
session data.
• Example :
$_SESSION['views']=1;
