It has for years. Every variable in a local scope (in a function) is local. You have to use: Global($var) to get at a global variable. > unset() is not a proper solution when using many variables > under different scopes. solution to what?

You don't get scopes like that, like you do in C (may be nice though). You get a new scopt in a function definition. > The above code should print: > whizkidfaisal > once $str inside the code block is declared to be local for that > particular scope.
