如何使包含路径通用？ [英] How to make the include path universal?

问题描述

我是php新手，有asp背景。非常感谢所有的帮助。


今天我在包含的文件中使用了include函数：


*** ************

consumer.php：<？包括inc.php ？>


inc.php：<？包括Common / functions.php ？>


functions.php：所有页面使用的常用功能

***************


如果在

<？中指定的路径，这可以正常工作包括Common / functions.php ？>

是相对于调用页面的路径的消费者.php


我希望能够指定<？包括inc.php ？>在每一页都不管

如果它嵌套在一个目录中。


在asp中我会使用这样的绝对路径：/Common/functions.php并且

会起作用。

当使用这样的路径时，PHP接近它：c：/website/site1/Common/functions.php


但是当我将页面从开发服务器转移到

实时服务器因为没有c：/ website / site1

$ b时会中断$ b我的下一个猜测是我可以用这样的变量来解决这个问题：$ docroot

.." /Common/functions.php"但是我在哪里可以在中心位置指定$ docroot？

（我会在asp的global.asa中这样做）


_SERVER ["当我请求它时，DOCUMENT_ROOT"是空白的，如果我理解

它是否正确，我可以在php.ini中设置它。问题是该值对于包装盒上的所有网站都持有

。


我是php的新手，所以如果我没有意义而不是让我直截了当:)


干杯，

Hi,

Im new to php and have a background in asp. All the help is very much appreciated.

today I was using the include function in a file that itself gets included :

***************
consumer.php : <? include "inc.php" ?>

inc.php : <? include "Common/functions.php" ?>

functions.php : common functions that all pages use
***************

This works fine if the path that''s specified in
<? include "Common/functions.php" ?>
is relative to the path of the calling page consumer.php

I want to be able to specify <? include "inc.php" ?> in every page no matter
if its nested in a directory or not.

In asp I would use absolute paths like this : /Common/functions.php and it
would work.
PHP comes close to it when using paths like this : c:/website/site1/Common/functions.php

But thus breaks when I transfer the pages from the development server to
the live server cause there is no c:/website/site1

My next guess was that I could solve this with a variable like this : $docroot
.. "/Common/functions.php" but where do I specify $docroot in a central location?
(I would do this in asp''s global.asa)

_SERVER["DOCUMENT_ROOT"] is blank when I request it and, if I understand
it correclty, I can set it in the php.ini . The problem is this value holds
for all the sites on the box.

I''m new to php so if I don''t make sense than pls put me straight :)

Cheers,
