the $_SESSION array is available everywhere. I seem to be able to access it within a function without declaring it as a global. It is customary to declare globals that you intend to access in a function (almost everything undeclared is assumed to be local to the function). Other exceptions that I know about like the session array are; $_GET, $_POST, and $GLOBALS, and there could be others.
Even with the "register globals" PHP option turned on (this will cause all $_GET, $_POST, and $_SESSION variables to be defined automatically before you execute, I believe you still need to declare the globals you intend to use in a function, so accessing things from anywhere, for the most part is not directly available (I can't recall a time when it ever was), with the exceptions mentioned above. I personally like the way PHP does things just fine, Warren Vail -----Original Message----- From: craig [mailto:[EMAIL PROTECTED] Sent: Wednesday, February 18, 2004 3:08 PM To: Php Subject: [PHP] functions and session variables Hi, I just want to verify something that seems counterintuitive to me. Do you have to pass session variables to functions? It would seem to me that they should be available anywhere. I took a cursory look through the manual, but didn't see anything relevant.
