preg_replace_callback(), how to pass function argument/param?

Hi, This is probably simple to answer for most of ya'll, but... preg_replace_callback($f, 'mah_processTags', $text); Besides the matches, how would I pass function args/param to mah_processTags()? For example, I would like to do something like this: preg_replace_callback($f, 'mah_processTags($arg1)', $text); function mah_processTags($matches, $arg1) { ... } Is this even possible? I just want to pass-in $arg1 along with the matches. :) Possible? Many thanks in advance!!!
