Anmerkungen
Hinweis: Das interneEncoding oder das mit mb_regex_encoding() festgelegteZeichenencoding wird als Zeichenencoding für diese Funktion genutzt.
Warnung
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.
