Finding matches is the hard part; after that, it's just string replacement. Assuming your string isn't excessively long, the operation is fairly trivial.

Is it right up there with preg_match? preg functions might be slow because the it scans the string several times depending on how many () you have in the regex.

It would be interesting to see the results summarized for various search lengths, particularly searching short strings. Thanks for running the test and posting it !
