Notice the plus after \w+ 

 $msg = preg_replace('/<b>(\w+)<\/b>/', '9999', $msg);

$msg = preg_replace('#<b>(\w)*<\/b>#', '9999', $msg);

Your \w does not match. I don't find my regex manual right now, but use something like .*.

You're missing the quantity token. That would only match one character long strings between the <b> tags.

$msg = preg_replace('/<b>(\w*)<\/b>/', '9999', $msg);
