mb_detect_order (PHP 4 >= 4.0.6, PHP 5) mb_detect_order --
Set/Get character encoding detection order
Descriptionmixed 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 an 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 <?php
/* 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());
