I am new to this and don't want to just go and change my or a colleague's php.ini.
I have Windows and he has Ubuntu set up.
I have 2 pages login.php and main.php with the following code at the top of each page
if(session_id() == '') { session_start(); }
I set a session variable to 1 or 0 depending if the user loggin in is a admin or not.
after clicking login you are taken to main.php. At the top of the page I did a print_r($GLOBALS) and I can see quite a lot of the global variables including the $_SESSION['admin'] entry.
On my colleague's pc there is only about 5 globals showing and $_SESSION is not there.
Is it a php.ini setup issue? Where do I start looking to fix this?
You have to call session_start(); in every page. – Naktibalda
Right
php.ini shouldn't have anything to do with this. – serakfalcon
Wrong
Then why it works on one machine and not on the other? session.auto_start in php.ini
session.auto_start Boolean
session.auto_start specifies whether the session module starts a session automatically on request startup. Defaults to 0 (disabled).
To not depend on that, you need to have
session_start();
On top of every page where you want to access or manipulate session data.
