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;
