Yes. if you use astahost free hosting service on this free hosting server, you don't need to use these functions, just set the superglobal variable $_SESSION; and thats all, everything is on the PHP Manual, when PHP6 comes, it will be the best/easiest scripting/programming language, most of the problems will be removed, but most of the servers will still run on php4 so you all "must" write the code to work on all php4 php5 and php6 and even php3 if you have time.

I recommend to go through the php manual user comments not in a day but time with time, when you write something big, to look up the manual and check the function you use what can it do and how to use it and with time you'll be a pro.

Well for now (for me) it's basically what ever works works, when I am happy with features and functioning I'll go through the whole lot and remove redundant code and fix things up.

OK Quatrax. That answered my questions. I think this thread may be deemed closed.

Actually whenever you want to use (or read) session variables you must always start a session using session_start() the you can
You must use session_start() to assign or use $_SESSION variables. It is a good practice to place the session start at or very near the beginning of your script to avoid the error about resending headers.

Yeah Lol but it can be hard to work out how to do Lol not to easy at all
