session_destroy(); not working

[DaRNCaT]

I'm trying to destroy the shopping cart session once the items have been purchased, but the session seesm to persist, and I don't know how to stop it.

I've used

session_destroy();

unset ($_SESSION['PHPSESSID']);
session_destroy();

and

unset ($_SESSION['cart']);
session_destroy();

None of which work, what am I doing wrong?????

----------------------------------------
Sometimes, when my code just won't behave, I take it outside and make it listen to britney spears music, and when it comes back it's really well behaved. I wonder if it's suffering from post tramatic stress syndrome now..

you need to do it like this:

session_start();
session_unset();
session_destroy();

if you used a session name, don't forget to mention it in the session_start statement

Hi, thanks for that but I've already tried that, I'm wondering if it's not working because I'm swapping from a secure zone to a non secure zone or something?

I have this on a secure page,

<?php
session_start();
session_unset();
session_destroy();
do some database stuff
?>

this then goes to an unsecure page - index.php which still shows the cart with it's contents, I've tried putting this in the index page

 session_start();
  if ($_SERVER['HTTP_REFERER'] == "[URL unfurl="true"]https://secure6.webhost-dns.net/~icesplic/php_paypal/success.php"){[/URL]
  session_destroy();
  }

but that doesn't work either, I know it's got to be something simple, but no matter how I fiddle around it seems to persist.

I always liked

$_SESSION=array();

Good'n simple.

hi skiflyer,
can you explain how to use it? as I get errors- I read the manual but I got confused, they recommened so many different things, and I tried them all, I think I'm just mixing them too much or not putting in things which should be there.
thanks

<?php

session_start();

echo '<pre>';
print_r($_SESSION);
echo '<hr />';
$_SESSION=array();  //session is now empty
print_r($_SESSION);
echo '</pre>';
?>

I've tried this

<?php
  // declare the session variables we want access to inside the function 
  session_start();
  if ($_SERVER['HTTP_REFERER'] == "[URL unfurl="true"]https://secure6.webhost-dns.net/~icesplic/php_paypal/success.php"){[/URL]
  $_SESSION=array();
  }
  if(!$_SESSION['items']) $_SESSION['items'] = '0';
  if(!$_SESSION['total_price']) $_SESSION['total_price'] = '0.00';
?>

And it's still not working, I checked the page info, and it says there is no referring URL, is this something to do with it comming from a secure page?
How on earth do I get rid of the sodding session???
