note 50397 deleted from function.preg-replace by tularis

Note Submitter: php at ihid dot co dot uk ---- In the function : $xml = preg_replace("asd", "\$1".$text."\$2", $xml); if text starts or finished with a number you will have unexpected behaviour. If $text = "3asd" for instance, the function will be $xml = preg_replace("asd", "\$13asd\$2", $xml); Rather than trying to parse $1 like we want, it will try to use $13, giving a very different result. Confused me for ages.
