mb_detect_order вЂ” Set/Get character encoding detection order
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.
Note: 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.
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 */
/* Set detection order by array */
$ary = "ASCII";
$ary = "JIS";
$ary = "EUC-JP";
/* Display current detection order */
echo implode(", ", mb_detect_order());
