Note Submitter: sam at wyvern dot com dot au ---- I note that you appear not to be able to use a back-reference inside a quantifier, so this doesn't work: preg_match('#^((\d+)\x00(\d+)\x00(.{\1})(.{\2}))+#', $data, $match) this is unfortunate, as this is a very useful idea - being able to proccess data with specified lengths in it. Instead it has to be done manually with excessive substr() usage... ---- Reason: bad code
