The beauty of this is you can have session_start(); session_register("x"); session_register("y"); session_register("z"); In a prepended file and you will now have a set of global variables $x, $y, $z that follow your user everywhere, with no extra work (as long as you are happy with cookies). A nice way of using this is to use arrays such as $USER_INFO registered. Now you can keep on adding more detail to $USER_INFO such as $USER_INFO["userid"], $USER_INFO["name"], $USER_INFO["theme"] or whatever. The question i have, is how could i make these variables "Protected" so no developer on my site decides that s/he wants to set $USER_INFO["userid"] = strtoupper($USER_INFO["userid"]) Whilst a simple change may not match the db or whatever. So basically once the user is logged in i want $USER_INFO to remain the same. Any ideas? mn -----Original Message----- From: Carroll Barrett [mailto:cbarrett@inalt.com] Sent: Tuesday, July 11, 2000 2:37 AM To: Brian T. Allen; Ray Parish; php-general@lists.php.net Subject: Re: [PHP] Sessions Brian/Ray, That's not how sessions work. A registered variable's value is saved at the end of the script, not when it is registered. Look at these 2 scripts: session1.php <?php session_start(); $x="Empty"; session_register("x"); $x="Full"; header("Location: session2.php"); ?> session2.php <?php session_start(); echo("x = $x"); ?> The result of calling session1.php in my browser is x = Full This would not be true if a variable's value was saved when it was registered instead of at the end of the script.
