mb_convert_encoding Convert a string from one character encoding to another &reftitle.description; arraystringfalsemb_convert_encoding arraystringstring stringto_encoding arraystringnullfrom_encoding&null; Converts string from from_encoding, or the current internal encoding, to to_encoding. If string is an &array;, all its &string; values will be converted recursively. &reftitle.parameters; string The &string; or &array; to be converted. to_encoding The desired encoding of the result. from_encoding The current encoding used to interpret string. Multiple encodings may be specified as an &array; or comma separated list, in which case the correct encoding will be guessed using the same algorithm as mb_detect_encoding. If from_encoding is omitted or &null;, the mbstring.internal_encoding setting will be used if set, otherwise the default_charset setting. See supported encodings for valid values of to_encoding and from_encoding. &reftitle.returnvalues; The encoded &string; or &array; on success, &return.falseforfailure;. &reftitle.errors; As of PHP 8.0.0, a ValueError is thrown if the value of to_encoding or from_encoding is an invalid encoding. Prior to PHP 8.0.0, a E_WARNING was emitted instead. &reftitle.changelog; &Version; &Description; 8.2.0 mb_convert_encoding will no longer return the following non text encodings: "Base64", "QPrint", "UUencode", "HTML entities", "7 bit" and "8 bit". 8.0.0 mb_convert_encoding will now throw a ValueError when to_encoding is passed an invalid encoding. 8.0.0 mb_convert_encoding will now throw a ValueError when from_encoding is passed an invalid encoding. 8.0.0 from_encoding is nullable now. 7.2.0 This function now also accepts an &array; as string. Formerly, only &string;s have been supported. &reftitle.examples; ]]> &reftitle.seealso; mb_detect_order UConverter::transcode iconv
