$correct = array("0","1","2","3","4","5","6","7","8","9","4","5","6");
$wrong = array("٠","١","٢","٣","٤","٥","٦","٧","٨","٩","۴","۵","۶");

Answer 1

Use this code:-

$t = "۰۱۲۳٤٥٦";
$text = preg_replace(
            array("٠","١","٢","٣","٤","٥","٦",),
            array("0","1","2","3","4","5","6",),
            $t );
