I quite agree that many regexes are 'write only', but I don't think
that that means that using substr and friends is necessarily any
clearer. I sometimes find that a nested mass of string functions is
even more confusing - at least a regex has a fixed grammar. I've just
written a load of stuff that uses preg_replace_callback that I'm
quite pleased with.
