自制一个小小的网站,其中一个功能总是有问题,求各位解答?
one.php:(开始运行的入口)

<br />

	define('LOCALSHOP_PATH', dirname(__FILE__).DIRECTORY_SEPARATOR);<br />
	//echo LOCALSHOP_PATH;<br />
	<br />
	require_once LOCALSHOP_PATH.'/base.php';<br />
	$mls = new MLS();<br />
	$mls->Load('front/includes/', 'dindex.phdp');  // 这是错误的,但为什么这里同样正确显示?<br />
        $mls->Load('front/includes/', 'index.php');   // 这个才是真正文件名<br />

dir_list.php:(显示目录树结构用于在base.php中判断是否有该目录或文件)
