mb_detect_order Set/Get character encoding detection order arraymb_detect_order mixedencoding-list mb_detect_order sets automatic character encoding detection order to encoding-list. It returns &true; for success, &false; for failure. encoding-list is array or comma separated list of character encoding. ("auto" is expanded to "ASCII, JIS, UTF-8, EUC-JP, SJIS") If encoding-list is omitted, it returns current character encoding detection order as array. This setting affects mb_detect_encoding and mb_send_mail. mbstring currently implements following encoding detection filters. If there is an invalid byte sequence for following encoding, 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. ]]> See also mb_internal_encoding, mb_http_input, mb_http_output and mb_send_mail.
