	$numargs = func_num_args();
	if($numargs>1){
		$out = '';
		ob_start();
		echo "<div style='background-color:#FFCC33;border:1px solid black;margin:3px;padding:5px;'>";
		for($a=0;$a<$numargs;$a++)
		print_a(func_get_arg($a));
		echo "</div>";
		$out .= ob_get_contents();
		ob_end_clean();
		echo $out;
	}else{

		$a = func_get_arg(0);
		$a = (is_bool($a))?(($a)?'true':'false'):$a;
		print_r($a);
