Fwd: [PHP] SESSIONS

Copying list as new Inbox seems to be missing a reply-all choice Bastien ---------- Forwarded message ---------- From: *Bastien Koert* <phpster@gmail.com> Date: Thursday, January 1, 2015 Subject: [PHP] SESSIONS To: erosenberg@hygeiabiomedical.com Ethan, As was explained in another post, sessions DO NOT WORK when you call shell_exec because the browser the user is using holds the session cookie WHICH IS NOT AVAILABLE during a shell_exec This is totally expected behavior. If you need to call the second script via a cron for example, no session variables will exist. Your script would have to generate those values (perhaps from a database call to some table) to have those available in the script. If your first script is calling shell_exec ( calling shell_exec from a script to another script in processing a browser call is just weird) then you would have to pass the session values you need in the shell_exec call as parameters.
