HTTP_POST_VARS and passing by reference

Hello, I'm attempting to make a function to which I can pass my form variables, to wit: clean_input($HTTP_POST_VARS); which will run through the array and clean up the variables. However, the passing by reference is giving me the screaming fits. No matter what I do, I can't seem to get the function to alter the actual array, and not a copy of it. I tried it with arraywalk(), but that produces a copy of the array, so I'm trying each() and list() like this: function clean_input(&$form_vars) { reset($form_vars); while ($element = each($form_vars)) { trim(strip_tags(stripslashes($element[1]))); } } but this just makes another copy. HTTP_POST_VARS still contains the ugly, raw input. Putting an "&" in front of $element in the while loop caused the script to crash. I know there should probably be another "&" somewhere, but I can't figure out where. Any help would be appreciated! -bryan ===== --------------------------------------------------------------------------- Schrodinger may have slept here. --------------------------------------------------------------------------- __________________________________________________ Do You Yahoo!?
