mb_detect_encoding - Detect character encoding

SYNOPSIS

       string mb_detect_encoding (string  $str, [mixed	$encoding_list = mb_detect_order()], [bool  $strict = false])

DESCRIPTION

	Detects character encoding in string$str.

PARAMETERS

	      o $str
		- The string being detected.

	      o $encoding_list
		-$encoding_list  is  list  of  character  encoding.  Encoding  order may be specified by array or comma separated list string.	If
		$encoding_list is omitted, detect_order is used.

	      o $strict
		-$strict specifies whether to use the strict encoding detection or not. Default is FALSE.

RETURN VALUES

	The detected character encoding or FALSE if the encoding cannot be detected from the given string.

EXAMPLES

       Example #1

	      mb_detect_encoding(3) example

	      <?php
	      /* Detect character encoding with current detect_order */
	      echo mb_detect_encoding($str);

	      /* "auto" is expanded according to mbstring.language */
	      echo mb_detect_encoding($str, "auto");

	      /* Specify encoding_list character encoding by comma separated list */
	      echo mb_detect_encoding($str, "JIS, eucjp-win, sjis-win");

	      /* Use array to specify encoding_list  */
	      $ary[] = "ASCII";
	      $ary[] = "JIS";
	      $ary[] = "EUC-JP";
	      echo mb_detect_encoding($str, $ary);
	      ?>

mb_detect_order - Set/Get character encoding detection order

SYNOPSIS

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

DESCRIPTION

	Sets the automatic character encoding detection order to $encoding_list.

PARAMETERS

	      o $encoding_list
		-$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(3)   and
		mb_send_mail(3).  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.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      mb_detect_order(3) 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
