Predefined or not, it's still a variable. If you want a variable inside of your function to have the value of a variable outside of your function, then you have to make it global. $PHP_SELF inside of your function has no value because it's relative to the function, not the script. Just like $a inside of a function wouldn't have a value unless you assigned one to it. Using "global $PHP_SELF" at the beginning of your function (or method, same thing) will now make the variable $PHP_SELF have the same value as it does outside of your function. > I read about variable scope and it says nothing about predefined > variables. > So how will using the $_SERVER associate array help me with this?

If anyone else has any thoughts or > explainations for me to understad this then that would be great. $_SERVER['PHP_SELF'] will always work, regardless of variable scope or register_globals setting. The $_SERVER array is a superglobal, so it'll have the same value inside your method or outside of it, without you having to do anything special. Hope that helps. ---John W. Holmes...
