Re: $_post and array question

Thanks for help Daniel Clark. I know i must use isset function but that was not the issue. But thanks anyway:) Curt Zirzow thanks for your reply also. But that has nothing to do with reference. If you use reference or not.. it still would not result in an error (hee... I want an error :P) Matt Matijevich thanks for your reply as well :) My function is already declared something like this: function testX($testArr) { $arr_test = $testArr; return $arr_test; } Even if you send a reference parameter (&$testArr).. the outcome will not result in an error. I guess somehow PHP does something to the function argument if it does not exist: creating it and give it the NULL value. But this should at least give us a warning because it could result in unwanted code! But i dunno know this for sure. Could anybody help me on this?
