Set/Get the internal character encoding

Параметри

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.

Значення, що повертаються

If encoding is set, then Повертає true у разі успіху або false в разі помилки. In this case, the character encoding for multibyte regex is NOT changed. If encoding is omitted, then the current character encoding name is returned.

Помилки/виключення

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.
