    Beschreibung

    mb_internal_encoding(?string$encoding = null): string|bool

    Set/Get the internal character encoding

    Parameter-Liste

    encoding

    encoding is the character encoding name used for the HTTP input character encoding conversion, HTTP output character encoding conversion, and the default character encoding for string functions defined by the mbstring module. You should notice that the internal encoding is totally different from the one for multibyte regex.

    Rückgabewerte

    If encoding is set, then Gibt bei Erfolg true zurück. Bei einem Fehler wird false zurückgegeben. In this case, the character encoding for multibyte regex is NOT changed. If encoding is omitted, then the current character encoding name is returned.

    Fehler/Exceptions

    As of PHP 8.0.0, a ValueError is thrown if the value of encoding is an invalid encoding. Prior to PHP 8.0.0, a E_WARNING was emitted instead.
