[RESOLVED] PHP - Clearing up variables

Hi

Another quick and easy question.

Once I'm at the bottom of the php file, so I need to unset any/all the variables I used ?
Also, if I destroy a session, will that clear the session variables as well ?

Just curious, and want to try to get into some good practices...

$_SESSION['x'] = 2; // new unrelated array 
session_write_close(); 
// saved session contains x => 1

It is not necessary to unset all of your variables from your page.

When you destroy a session, all session variables are... destroyed, so they no longer exist.

Your post didn't answer any question the OP asked.

Thanks :)
