I have upgraded PHP on my 2008 std server from PHP 5.2 to PHP 5.3. Following the upgrade, sessions no longer work correctly.

I have copied over the settings from my PHP.ini files which are applicable and configure new settings in line with the server or PHP's recommendations.

PHP executes fine correctly, however session data does not get saved.

I have session data stored in c:\temp. For each session created, I can see the session file in this folder. However no information gets written into the session file. Permissions wise, IUSR and EVERYONE has write access to this folder.

If I downgrade to PHP 5.2, sessions are saved correctly and the site functions correctly.

I have followed advise to ensure my code is optimised. closing session files correctly and forcing a session reset.

I'm stumped.

  • Adding the exact version of PHP in your question will be helpful to check against bugs.

  • I see a number of session variables deprecated in php 5.3.X. Please refer php.net/manual/en/migration53.deprecated.php and confirm that you are not using them. If you are not using them in your code and still getting this error, you may need to provide the code snippet for further review as there is no session related bugs reported yet for PHP 5.3.6.

the problem was related to the last session name "(@#!_D@R&$%(){*@)_D_296", it was somehow invalidating the entire browser session, removing all data from the session.

After removing "(@#!_D@R&$%(){*@)_D_296" from the session name, the login session started working again.
