설명

mixed mb_detect_order ([ mixed $encoding_list = mb_detect_order() ] )

Sets the automatic character encoding detection order to encoding_list.

인수

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-JP

For ISO-8859-*, mbstring always detects as ISO-8859-*.

For UTF-16, UTF-32, UCS2 and UCS4, encoding detection will fail always.

반환값

성공 시 TRUE를, 실패 시 FALSE를 반환합니다.

예제

Example #1 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());
?>

Example #2 Example showing useless detect orders

; 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
