mb_detect

Description

array 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().

注: mbstring currently implements following encoding detection filters. If there is an invalid byte sequence for following encoding, encoding detection will fail.
注: 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.
例子 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

例子 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()); ?>
