mb_detect_order -- Set/Get character encoding detection order
Description
array mb_detect_order ([mixed encoding-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().
Note: mbstring currently implements following encoding detection filters. If
there is a invalid byte sequence for following encoding, encoding detection will fail.
Note: 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.

Example 1. Useless detect order example
; Always detect as ISO-8859-1
detect_order = ISO-8859-1, UTF-8
; Always detect as UTF-8, since ASCII/UTF-7 values are
; valid for UTF-8
detect_order = UTF-8, ASCII, UTF-7

Example 2. mb_detect_order() examples
/* Set detection order by enumerated list */
mb_detect_order("eucjp-win,sjis-win,UTF-8");
/* Set detection order by array */
$ary[] = "ASCII";
$ary[] = "JIS";
$ary[] = "EUC-JP";
mb_detect_order($ary);
/* Display current detection order */
echo implode(", ", mb_detect_order());
