如何取得路径返回父目录呢?
admin 和 date admin目录里的某文件要require date目录里的一个文件 怎么做啊?


require (dirname(__FILE__)."../date/my_class.php")

------解决方案--------------------
弄清 admin 和 date admin目录的关系再说
------解决方案--------------------

PHP code

if (!defined('DS'))
  define('DS',DIRECTORY_SEPARATOR);
$arr = explode(DS,dirname(__FILE__));
array_pop($arr);
require_once (implode(DS,$arr).DS."date".DS."my_class.php"); <div class="clear">
                 
              
              
        
            </div>
