if I were Richard Lynch I would mention that you probably want to backslash
your backslashes:
$find = "/\\b" . $search . "\\b/";
but then again if I were Richard Lynch I would probably assume that John Nichel

would I?
what would Richard Lynch say?
(no offence Richard!, Im just being playful :-)
(btw Richard is right about the backslashing!)
