mb_detect_order — Set/Get character encoding detection order
Sets the automatic character
encoding detection order to
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.
When setting the encoding detection order,
TRUE is returned on success or
FALSE on failure.
When getting the encoding detection order, an ordered array of the encodings is returned.
Exemplo #1 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());
Exemplo #2 Example showing useless detect orders
; 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
