mb_detect_order — Set/Get character encoding detection order
Sets the automatic character encoding detection order to encoding_list.
encoding_list is an 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 the current character encoding detection order as array.
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.
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
Returns TRUE on success or FALSE on failure.
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());
