php include_once不工作

Question

不工作的原因是什么？include_once？

这是我的文件夹层次结构:

/Php/Controls/GridView/GridView.php
/Php/Controls/Form/Form.php

在"Form.php"中:

include_once '../GridView/GridView.php';

我收到这个错误:

Warning: include_once(../GridView/GridView.php) [function.include-once]: failed to open stream: No such file or directory in ...Form.php on line 4

Warning: include_once() [function.include]: Failed opening '../GridView/GridView.php' for inclusion (include_path='.;C:\php\pear') in ...Form.php on line 4

如果您想了解更多信息,请告诉我.

在Form.php使用中

include_once dirname(__FILE__) . '/../GridView/GridView.php';

这会创建一个绝对路径,但相对于文件,它从中调用.
