Replace chars in multi-byte string.
In example, replacing 'f'=>'b', 'o'=>'e', 't'=>'r' and etc.

<?php
function mb_chars_replace($from, $to, $subj, $delSymb='_') {
     $nsubj='';
     preg_match_all('/(.)/u', $subj, $subj);$subj=$subj[1];
     if (!is_array($from)) {preg_match_all('/(.)/u', $from, $from);$from=$from[1];} 
     if (!is_array($to)) {preg_match_all('/(.)/u', $to, $to);$to=$to[1];}
     if (count($from)!==count($to)) return false;

     foreach($subj as $s) {
       foreach($from as $k=>$f) {
         if($s===$f) {
                    $s=$to[$k];
                    break;
         }
       }
       if($s!==$delSymb) $nsubj.=$s;
     }
    return $nsubj;
} 

//examples:

$from="fotber, ";
$to="berfot+_";

// or

$from=array("f","o","t","b","e","r",","," ");
$to=array("b","e","r","f","o","t","+","_");

//out:
echo mb_chars_replace($from,$to,"foot, beer"); //beer+foot
?>
