[PHP] Logout / Destroy Session

[brsy]

<?php
 
session_start();
session_destroy();
 
if(session_destroy()) {
    header("Location: http://pabbo.net/index.php");
}
 
?>

Would the if statement be valid?

You don't really need the if statement. Just do

<?php
session_start();
session_destroy();
header( "Location: http://pabbo.net/index.php");
?>

Okay thanks, but the if statement would still work, right?

Yeah it would work no doubt, but it's not necessary - it would be pointless code really.

Wouldn't it be better to unset a particular session, instead of all sessions?

You must be registered for see links

Why, when the user will be completely logged out? How would that be useful?

Because it's bad practice to unset ALL sessions, where as all you SHOULD be doing is unsetting the user related session.

Actually he's right, you may have other sessions set and don't want to destroy them. Using session_destroy will destroy all sessions you have on that web-server., where as using unset() you can just destroy specific sessions.
