note 91536 added to function.str-replace

Be careful when replacing characters (or repeated patterns in the FROM and TO arrays): For example: $arrFrom = array("1","2","3","B"); $arrTo = array("A","B","C","D"); $word = "ZBB2"; echo str_replace($arrFrom, $arrTo, $word); I would expect as result: "ZDDB" However, this return: "ZDDD" (Because B = D according to our array) To make this work, use "strtr" instead: $arr = array("1" => "A","2" => "B","3" => "C","B" => "D"); $word = "ZBB2"; echo strtr($word,$arr); This returns: "ZDDB" ---- Server IP: 69.147.83.197 Probable Submitter: 211.6.179.194 ---- Manual Page -- http://www.php.net/manual/en/function.str-replace.php Edit -- https://master.php.net/note/edit/91536 Del: integrated -- https://master.php.net/note/delete/91536/integrated Del: useless -- https://master.php.net/note/delete/91536/useless Del: bad code -- https://master.php.net/note/delete/91536/bad+code Del: spam -- https://master.php.net/note/delete/91536/spam Del: non-english -- https://master.php.net/note/delete/91536/non-english Del: in docs -- https://master.php.net/note/delete/91536/in+docs Del: other reasons-- https://master.php.net/note/delete/91536 Reject -- https://master.php.net/note/reject/91536 Search -- https://master.php.net/manage/user-notes.php
