php session
/*Sessions are stored on the server
Sessions are a way to carry data across multiple pages.
Typically if we set a variable on one page, it wouldn't be available
on the next page. This is where Sessions come in. Unlike cookies session
data is not stored on the user's computer. It is stored on the server.
In order to use session variables you have to start a session.
Every page, that you want to use that data in, you have to use
session_start.
If you want to unset one of these sessions you can use session_unset
youcan destry the session with session_destroy
*/

{ session_start(); // that will start the session
$_SESSION['name'] = htmlentities($_POST['name']);
$_SESSION['email'] = htmlentities($_POST['email']);
