PHP session_id changes between pages or when refreshing the page

The problem is that every time I refresh the page or when I change the page to another one, the session_id changes and new session file is created in session_save_path. Here is the initial part of my code:

<?php
    session_start();
    echo session_id();
    ...
?>

Obviously the session variables (which is the thing that I need) don't work.

A curious thing is that the page works fine on localhost but doesn't work when I try it on the server.

Thanks in advance.

Check this setting in your server: session.auto_start

This will cause session to be autostarted in each page whether you call session_start() or not.

Make sure that there are no phantom CRLFs or such stuff before session starts. In production the error_reporting can be off so it might not get caught, but the session might find difficulty getting written. This can sometimes cause this.

Looks like your directory with sessions is not writable.

That's why php generates a new session file each time. Check your chmod for sessions folder.

On your server, in php.ini check TTL for your cookies. session.cookie_lifetime defines how long the cookie will last in seconds (default is 0, which means until the browser is closed) and session.gc_maxlifetime defines how long before the data is deleted, also in seconds.

And make sure the session file isn't stored in a /tmp folder.
