mb_detect_order

(PHP 4>= 4.0.6, PHP 5)mb_detect_order -- Set/Get character encoding detection order

Description

mixed 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().

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

Замечание: 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.

Пример 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
