Ah.... I see. Sounds like you want a callback... There isn't a POSIX-regex function to do this. You need to use preg_replace_callback() instead. http://www.php.net/manual/en/function.preg-replace-callback.php Lets see.... function makeBold($matches) { return('<b>' . $matches[0] . '</b>'); } $t = "hello world"; echo(preg_replace_callback("(hello)", "makeBold", $t)); Let me know if that works for you.
