RE: [PHP] variables??

Okay, true. But they key here is the "act accordingly", meaning you sanitize and validate the variable before using it anywhere. Sometimes the way it's represented is that just using $_GET['var'] is going to make things more secure than using $var, which is not the case unless you know what exactly $_GET['var'] contains and how you're using it. ---John W.

No, it is more secure.  The problem with register_globals is that ALL variables become global - not just the ones you want to be.  Example: if(something) $authorized = true; if($authorized){ ...do something requiring security... } A hacker could easily go to script.php?authorized=1, and gain access.  If you only allow one variable in that ($_GET['var']), you will know that the variable is from an outside source, and can act accordingly. John W. Holmes wrote: It is considered more secure to declare the variable explicitly. $var = $_GET["var"]; Ummm... that's the same result as having register_globals on (basically). You're not helping anything and it's certainly not any more "secure". ---John W. Holmes... PHP Architect - A monthly magazine for PHP Professionals.
