mb_detect_order
(PHP 4 >= 4.0.6, PHP 5)
mb_detect_order — Set/Get character encoding detection order
说明
mixed mb_detect_order ([ mixed $encoding_list ] )Sets the automatic character encoding detection order to encoding_list.
参数
- encoding_list
-
encoding_list is an array or comma separated list of character encoding. See supported encodings.
If encoding_list is omitted, it returns the current character encoding detection order as array.
This setting affects mb_detect_encoding() and mb_send_mail().
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-JPFor 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
返回值
成功时返回 TRUE， 或者在失败时返回 FALSE.
范例
Example #2 mb_detect_order() examples
<?php
mb_detect_order("eucjp-win,sjis-win,UTF-8");
$ary[] = "ASCII";
$ary[] = "JIS";
$ary[] = "EUC-JP";
mb_detect_order($ary);
echo implode(", ", mb_detect_order());
?>
