The variables stored in the $GLOBALS array don't have to be declared as global within a function. They're already available within the function. To make a global variable available within a function's local namespace, you _either_: * pass it by reference: function cp(&$userPassword) * declare it as a global: global $userPassword * make it an element of the $GLOBALS array: $GLOBALS['userPassword'] (You could also pass by value, but then you're dealing with a copy of the variable instead of the variable itself.) -- CC
