This one is what you need. I don't think it is. The variable did not exist before the function was called and should STILL not exist afterwards. I believe when you pass by reference, the variable will exist after the call. Only if you created it during the call. <?php function foo(&$arg) { } foo($nonex); var_dump(isset($nonex)); ?> bool(false)
This is bad since future calls to 'isset' will suddenly start returning TRUE when they shouldn't.
