Note Submitter: tonicboy ---- @ad wow, that's very complex code for a simple function. why don't you just do: $clean = preg_replace("/[^0-9()\.\- ]/", "", $phone); i'm confused why you even want to keep any non-digit characters anyway. it's usually best practice to store phone numbers as digits-only. also, there's no need to use the multibyte version of strlen if you've just stripped out everything but single-byte characters. it's a small optimization but an optimization nonetheless.
