Why Does My PHP Session Data Disappear After a Refresh?

PHP Session Data Persists Unreliably

Despite apparent session initiation, session data inexplicably fails to persist across page refreshes and transitions. This issue stems from an unexpected alteration to the session save path by the web hosting provider.

Troubleshooting the Issue

With PHP version 4.4.7, the session save path is typically stored in "/var/php_sessions". However, in this case, the path had been changed to a non-existent directory.

Solution

To resolve the problem, the following steps were taken:

1. Contacting the hosting provider and requesting them to set the session path to a valid writable directory.

Additional Notes

• Setting ini_set('session.save_path','SOME WRITABLE PATH') directly in PHP scripts could have addressed the issue, but would have required manual updates in multiple files.
• It's essential to check with the hosting provider when faced with unexpected session behavior, as they may have implemented server-side modifications.
