If your text is in UTF-8 encoding, append the 'u' modifier to your regex pattern for Unicode support.
$text = preg_replace('/\bمرحبا بك\b/u', 'NEW', $text);

Is your text in UTF-8 encoding? If yes, can you post the original value of `$text`? – Inglis Baderson Jul 27 '13 at 14:13

Is it possible that you mixed up `\b` with `\B`? Because `\b` is for word character. – Inglis Baderson Jul 27 '13 at 14:30

No copy pasted your code and pasted in php interactive shell. If it's working for the question asker though, it's good. I don't need this to work for me. – Patrick Kostjens Jul 27 '13 at 14:32

**Important Note** : Your server php version shoud be at least PHP 4.3.5 check this: http://php.net/manual/en/reference.pcre.pattern.modifiers.php @AgreeOrNot thank you very much for giving me the key to start solve that problem – usama sulaiman Oct 08 '13 at 21:43

Don't add a \b at the end of your regex. The matching should work fine when you change your code into this:
$text = preg_replace('/\bمرحبا بك/', 'NEW', $text);
You cannot use \b at the end as well since there is a space in the word(s) you're trying to match. \b fails to match anything when there is a non word-character in the part you're trying to match.

@علاءمحمد, I updated my answer with an extra explanation about why that's not possible with what you're currently trying to match. – Patrick Kostjens Jul 27 '13 at 14:18

Just take str_replace. No need for regex.
$text = 'hello bمرحبا بك world';
echo str_replace('bمرحبا بك', 'NEW', $text);
