unset($_SESSION['var']) not working on linux server...

tunage

Ive got my website working fine on my windows setup, but when i transfer it to a linux server, the session variables refuse to be destroyed.

session_destroy() works fine, but i want to unset certain sessions variables, not all of them. Ive tried doing $_SESSION['var'] = null, but that doesnt work. Ive checked the phpinfo for the linux server and it looks ok as far as i can tell - register globals is off, short_open_tag is on. Im using an .htaccess file just to point to my includes folder but thats it.

Has anyone else come across this problem or know what might be causing it?

Thanks in advance.

What version of php??

tunage

linux is running 4.3.1 and windows i running 4.3.0

Do you use session_register(), session_is_registered() or session_unregister() as well as direct access to the $_SESSION array??

EDIT:
Discard that. I just noticed that you already said register_globals is off.

Try this simple test script just to make sure the problem isn't being caused elsewhere in your script -

<?php
session_start();

if (isset($_GET['reset'])) {
	unset($_SESSION['count']);
	}

if (!isset($_SESSION['count'])) {
	$_SESSION['count'] = 0;
	echo "Just registered var";
	}
else {
	$_SESSION['count']++;
	echo 'Count: '.$_SESSION['count'];
	echo '<br><a href="?reset=1">Reset</a>';
	}
?>

Refresh the page a couple of times to see the counter increment and then click reset and se if you get the "Just reg.." msg.

Thanks for your help nnichols, found out what was wrong, i had my .htaccess file pointing to an old functions folder which was virtually the same apart from the function that was deleting the sessions vars. grrr! :rolleyes:
