Loads of bogus ones though. array_search() also completely the wrong tool for the job - the code you posted is much more complicated and slower than it needs to be. That whole palaver that you go through to produce $reduced could be replaced with: $reduced = array_merge(array(), array_unique($str)); That nested loop you use to produce $final would be rather simpler and faster if you just flipped $reduced and used a hash lookup. $charmap = array_flip($reduced); foreach ($str as $char) { $final[] = $charmap[$char]; } -robin
