Anmerkungen

Hinweis:

Die interne Kodierung oder die mit mb_regex_encoding() festgelegte Zeichenkodierung wird als Zeichenkodierung für diese Funktion genutzt.

Warnung

Der Modifikator e sollte niemals verwendet werden, wenn mit Eingaben gearbeitet wird, die als nicht vertrauenswürdig gelten. Es erfolgt keine automatische Maskierung wie sie von der Funktion preg_replace() bekannt ist. Wenn dies nicht beachtet wird, führt es in der Anwendung höchstwahrscheinlich zu Sicherheitslücken bezüglich der Ausführung von entferntem Code.
