Descrizione

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

Set/Get the internal character encoding

Elenco dei parametri

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.

Valori restituiti

If encoding is set, then Restituisce true in caso di successo, false in caso di fallimento. In this case, the character encoding for multibyte regex is NOT changed. If encoding is omitted, then the current character encoding name is returned.

Errori/Eccezioni

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.
