php include_once not working
提问by Jean-Philippe Leclerc
What would be the reasons of a non working include_once?
不工作的 include_once 的原因是什么？
Here's my folder hierarchy:
这是我的文件夹层次结构：
/Php/Controls/GridView/GridView.php
/Php/Controls/Form/Form.php
In "Form.php":
在“Form.php”中：
include_once '../GridView/GridView.php';
I'm getting this error:
我收到此错误：
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
Please tell me if you want more information.
如果您需要更多信息，请告诉我。

In Form.phpuse
在Form.php使用
include_once dirname(__FILE__) . '/../GridView/GridView.php';
This creates an absolute path, but relative to the file, where its called from.
这将创建一个绝对路径，但相对于调用它的文件。
回答by Tyler Carter
It can't find the file.
它找不到文件。
You should use a full path, like /Php/Controls/GridView/GridView.phpinstead of a relative one.
您应该使用完整路径，/Php/Controls/GridView/GridView.php而不是相对路径。

Try this:
尝试这个：
include_once './php/Controls/GridView/GridView.php';

Hope I'm not too late on this one but I thought this might be what you're looking for:
希望我在这方面还不算太晚，但我认为这可能是您要找的：
include_once realpath(dirname(__FILE__)."/../GridView/GridView.php");
Using realpath()allows you to include files even from outside your server document root directory.
使用realpath()允许您包含甚至来自服务器文档根目录之外的文件。
