session unset and session unregister

[fernandodonster]

what is the defference between session unset and session unregister?help me?

[bradgrafelman]

Have you tried reading the manual? [man]session_unset/man vs. [man]session_unregister/man - one clears all variables, one targets a specified variable.

Although, it should be noted that [man]session_unregister/man is really no longer used much, as it's better to unset() the variable in the $_SESSION superglobal array (see: [man]variables.predefined[/man]). Of course, the manual page for [man]session_unregister/man explains all of this as well...

Don't use session_register, prefer the superglobal $_SESSION.

To unset a session variable you can then do unset($_SESSION['whatever'])

To clear the whole session out,

$_SESSION = array();

Should work.
