note 78868 added to function.strpos

A further implementation of the great rstrpos function posted in this page. Missing some parameters controls, but the core seems correct. <?php // Parameters: // // haystack : target string // needle : string to search // offset : which character in haystack to start searching, FROM THE END OF haystack // iNumOccurrence : how many needle to search into haystack beginning from offset ( i.e. the 4th occurrence of xxx into yyy ) function rstrpos ($haystack, $needle, $offset=0, $iNumOccurrence=1) { // $size = strlen ($haystack); $iFrom = $offset; $iLoop = 0; // do { $pos = strpos (strrev($haystack), strrev($needle), $iFrom); $iFrom = $pos + strlen($needle); } while ((++$iLoop)<$iNumOccurrence); // if($pos === false) return false; // return $size - $pos - strlen($needle); } ?> ---- Server IP: 69.147.83.197 Probable Submitter: 87.16.235.186 ---- Manual Page -- http://www.php.net/manual/en/function.strpos.php Edit -- https://master.php.net/note/edit/78868 Del: integrated -- https://master.php.net/note/delete/78868/integrated Del: useless -- https://master.php.net/note/delete/78868/useless Del: bad code -- https://master.php.net/note/delete/78868/bad+code Del: spam -- https://master.php.net/note/delete/78868/spam Del: non-english -- https://master.php.net/note/delete/78868/non-english Del: in docs -- https://master.php.net/note/delete/78868/in+docs Del: other reasons-- https://master.php.net/note/delete/78868 Reject -- https://master.php.net/note/reject/78868 Search -- https://master.php.net/manage/user-notes.php
