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 FALSE
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() 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 ()); ?>
