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

	      mb_substitute_character(3) example

	      <?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_convert_variables - Convert character code in variable(s)

SYNOPSIS

       string mb_convert_variables (string  $to_encoding, mixed  $from_encoding, mixed	&$vars, [mixed	&$...])

DESCRIPTION

	Converts character encoding of variables $vars in encoding $from_encoding to encoding $to_encoding.

       mb_convert_variables(3)	join  strings  in  Array  or  Object to detect encoding, since encoding detection tends to fail for short strings.
       Therefore, it is impossible to mix encoding in single array or object.

PARAMETERS

	      o $to_encoding
		- The encoding that the string is being converted to.

	      o $from_encoding
		-$from_encoding is specified as an array or  comma  separated  string,	it  tries  to  detect  encoding  from  $from-coding.  When
		$from_encoding is omitted, detect_order is used.

	      o $vars
		-$vars	is  the  reference to the variable being converted. String, Array and Object are accepted. mb_convert_variables(3) assumes
		all parameters have the same encoding.

	      o $...
		- Additional $vars.

RETURN VALUES

	The character encoding before conversion for success, or FALSE for failure.

EXAMPLES

       Example #1

	      mb_convert_variables(3) example

	      <?php
	      /* Convert variables $post1, $post2 to internal encoding */
	      $interenc = mb_internal_encoding();
	      $inputenc = mb_convert_variables($interenc, "ASCII,UTF-8,SJIS-win", $post1, $post2);
	      ?>
