mb_convert_encoding — Convert a string from one character encoding to another
$string, string$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.
stringto_encodingThe 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.
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.
| Version | Beschreibung |
|---|---|
| 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 Strings have been supported. |
