Before preg_replace_callback() was introduced, preg_replace() used to have another an "f" modifier which had similar functionality. I'm not sure whether that modifier was available back in PHP3, but here's the relevant quote about "f" from an old set of PCRE Syntax docs: > F > If this modifier is set, preg_replace() treats the replacement parameter as a > function name that should be called to provide the replacement string.

If I recall correctly (which I may not), an example would look something like this: $output=preg_replace("/(\w+)/f","'***' . strtolower($1) . '***'",$input); -- CC
