note 90995 added to function.preg-match-all

@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. ---- Server IP: 64.71.164.2 Probable Submitter: 115.75.73.30 ---- Manual Page -- http://www.php.net/manual/en/function.preg-match-all.php Edit -- https://master.php.net/note/edit/90995 Del: integrated -- https://master.php.net/note/delete/90995/integrated Del: useless -- https://master.php.net/note/delete/90995/useless Del: bad code -- https://master.php.net/note/delete/90995/bad+code Del: spam -- https://master.php.net/note/delete/90995/spam Del: non-english -- https://master.php.net/note/delete/90995/non-english Del: in docs -- https://master.php.net/note/delete/90995/in+docs Del: other reasons-- https://master.php.net/note/delete/90995 Reject -- https://master.php.net/note/reject/90995 Search -- https://master.php.net/manage/user-notes.php
