note 70001 added to function.array-search

Checks that array value STARTS with the string(needle), while other functions require an exact match OR the needle can be anywhere within. This function can be manipulated to END with the needle if needed <?php // returns first key of haystackarray which array valuestring starts with needlestring, is case-sensitive function arrayHaystackStartsWithNeedleString($haystackarray, $needlestring) { if (is_array($haystackarray)) { // confirms array $needlelength = strlen($needlestring); // length of string needle foreach ($haystackarray as $arraykey => $arrayvalue) { // gets array value $arraypart = substr($arrayvalue, 0, $needlelength); // first characters of array value if ($needlestring == $arraypart) { // did we find a match return $arraykey; // return will stop loop } // end match conditional } // end loop } // end array check return false; // no matches found if this far } ?> I haven't speed tested this, but it should be pretty quick. ---- Server IP: 66.163.161.117 Probable Submitter: 68.104.56.193 ---- Manual Page -- http://www.php.net/manual/en/function.array-search.php Edit -- https://master.php.net/note/edit/70001 Del: integrated -- https://master.php.net/note/delete/70001/integrated Del: useless -- https://master.php.net/note/delete/70001/useless Del: bad code -- https://master.php.net/note/delete/70001/bad+code Del: spam -- https://master.php.net/note/delete/70001/spam Del: non-english -- https://master.php.net/note/delete/70001/non-english Del: in docs -- https://master.php.net/note/delete/70001/in+docs Del: other reasons-- https://master.php.net/note/delete/70001 Reject -- https://master.php.net/note/reject/70001 Search -- https://master.php.net/manage/user-notes.php
