                                mb_detect_order

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

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().

     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());
   ?>

   See also mb_internal_encoding(), mb_http_input(), mb_http_output() and
   mb_send_mail().
