Sets the automatic character encoding detection order to encoding_list
.
encoding_list
is an array or comma separated list of character encoding. See supported encodings.
If encoding_list
is omitted, it returns the current character encoding detection order as array.
This setting affects mb_detect_encoding() and mb_send_mail().
mbstring currently implements the following encoding detection filters. If there is an invalid byte sequence for the following encodings, encoding detection will fail.
UTF-8, UTF-7, ASCII, EUC-JP,SJIS, eucJP-win, SJIS-win, JIS, ISO-2022-JP
For ISO-8859-*, mbstring always detects as ISO-8859-*.
For UTF-16, UTF-32, UCS2 and UCS4, encoding detection will fail always.
Returns TRUE
on success or FALSE
on failure.
