Set/Get character encoding detection 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
mbstring currently implements following
encoding detection filters. If there is a invalid byte sequence
for following encoding, encoding detection will fail.
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());
