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
