php strstr not detecting substring in a arabic string

Question

Can anyone please tell me ,How to make string matching function work with Arabic keywords? The Following keywords are detected as Unmatched in php. Though these are matching in normal browser searching.

    if (strstr('الهيئة العامة للقوى العاملة', 'قوى العامله') != false) {
       echo'in';
          } else {
          echo'out';
           }die;

Result comes as 'out'.

Thanks

Try this .. I have PHP Version 5.6.23

<?php 
$string = 'الهيئة العامة للقوى العاملة';
$find_me = 'قوى العاملة';
if (strstr($string, $find_me) != false) {
       echo'in';
          } else {
          echo'out';
           }die;

?>
