global variables inside of a function

Is there a way to access a session variables or server variables from inside a function? I have a function and was trying to use $PHP_SELF inside of it. I get a variable undefined error. Out side of the function it works fine. I don't want to parameter pass the global variables to the function, I know this would work, but I would have to many variables to pass. Example: function functionname() { echo $PHP_SELF; } Thanks, Mark. _________________________________________ Mark McCulligh, Application Developer / Analyst Sykes Canada Corporation www.SykesCanada.com mmcculli@SykesCanada.com
