(PHP 4 >= 4.0.6, PHP 5, PHP 7, PHP 8)
mb_convert_encoding — Convert a string from one character encoding to another
Beschreibung
$string, string $to_encoding, array|string|null $from_encoding = null): array|string|false
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.
Parameter-Liste
-
string -
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_encodingisnullor not specified, the mbstring.internal_encoding setting will be used if set, otherwise the default_charset setting.See supported encodings for valid values of
to_encodingandfrom_encoding.
Fehler/Exceptions
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.
