I never liked to use session but i had to in this case. the session contains an object used to store data will the user fill in a form the form is in 5 steps( 5 pages). to make sure that the session is clean if the user click on a link to another will filling in the form i use session_destroy but this seams to take forever i know the object gets a little big around 400Kb but server memory is 1.5Gb and i'm alone on it for now does anyone have a clue.

IF , ELSE , WHILE isn't that what life is all about

... can I see a snip of your code?

http://ca.php.net/function.session-destroy

<?php
session_unset(); 
session_destroy(); 
?>

This is what I use, but I don't know if that helps.

What kind of problems are you having? session_destroy() seems to be slow/hanging?

Yes thats what happens i will try Suzanne solution i didn't unset the sesson before destroying it.

this is the code that i put on every pages that are not in the form filling process

<?php
session_start();
session_destroy();
?>

ok i tried both of those and still the same thing

<?php
session_start();
session_unset();
session_destroy();
?>

<?php
session_start();
unset($_SESSION['myobject']);
session_destroy();
?>

You're not having these right in a row, are you?

<?php
1: session_start();
2: session_destroy(); 
?>

If you are, why? If you aren't, is there something happening between the start and stop that's a problem?

yes i am i do it to make sure that if the user go back to the form it will be empty (since the session contains the previously filled in values) so i do that on all pages that are not related to the form.

Humm now that i explain it i understand this is not optimal at all. since it will open and close the session even if the user never went to the form pages. :light: ok i will check for the referer before doing it.

Hey this gave me an idea i now clean up the session when back on the form instead this make code that look more logical, and working wich is certainly a good point thanks for your input.
