Great! Thanks!

But if these required three keys are messed up into the $_POST array, Is there a direct way to shift off elements at a specified key or index to remove them from an array? (I mean without a batch process) Something like: array_shift($array, $index) which of course is incorrect Although now I know I can write a code to search for a key and then splice it out from $_POST into another one.

I'm reading the online manual and many other sites before posting to newsgroups, As you can see, I'm not an expert programer but just a beginner. I'm trying to make a lightweight any-form-to-email script. The first 3 keys of the associative array ($_POST) are "recipient", "reply_email" and "subject". All other NAMED form elements will be mailed with this format: FORM NAME (key): FORM VALUE (value) - PhiSYS
