I want to check if a session is currently set, and if so do allow the page to run as normal (do nothing) if not create a session.
I had a look at another SO question, in which the following code was posted:
if ( empty( $_SESSION['login'] )) { } else { }
Would the easiest way to do this be to set something like $_SESSION['a'] for each session, and then run if(empty($_SESSION['a'])) to check if a session exists?
Then again, can you use a session variable without invoking session_start() in the first place, thus making it obsolete (I tried this yesterday, as an echo though, not an if statement to check that a variable was carrying through without realizing that session_start() needed to be invoked before I could echo the variable).
There's probably an easy way that's oft used, I just can't seem to find it.
Any help would be greatly appreciated!
