mb_substitute_character - Set/Get substitution character

SYNOPSIS

       mixed mb_substitute_character ([mixed  $substrchar = mb_substitute_character()])

DESCRIPTION

	Specifies a substitution character when input character encoding is invalid or character code does not exist in output character encoding.
       Invalid characters may be substituted NULL (no output), string or integer value (Unicode character code value).

	This setting affects mb_convert_encoding(3), mb_convert_variables(3), mb_output_handler(3), and mb_send_mail(3).

PARAMETERS

	      o $substrchar
		- Specify the Unicode value as an integer, or as one of the following strings:

		     o "none": no output

		     o "long": Output character code value (Example: U+3000, JIS+7E7E)

		     o "entity": Output character entity (Example: )

RETURN VALUES

	If $substchar is set, it returns TRUE for success, otherwise returns FALSE. If $substchar is not set, it returns the current setting.

EXAMPLES

       Example #1

	      <?php
	      /* Set with Unicode U+3013 (GETA MARK) */
	      mb_substitute_character(0x3013);

	      /* Set hex format */
	      mb_substitute_character("long");

	      /* Display current setting */
	      echo mb_substitute_character();
	      ?>

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);
	      ?>
