Note:
The internal encoding or the character encoding specified by mb_regex_encoding() will be used as the character encoding for this function.
Never use the e modifier when working on untrusted input. No automatic escaping will happen (as known from preg_replace()). Not taking care of this will most likely create remote code execution vulnerabilities in your application.
