PHP路径包含文件 [英] PHP Path to Include Files

问题描述

我有一个网站用的index.php。 在index.php拥有一批包括像文件

I have a site with an index.php. The index.php has a number of include files like

 <?php include_once('scripts/php/index_mainImageJoin.php');?>

我创建了一个新的文件夹断称为extrapages的根源，我将有一个有关于该网站的信息在里面的页面。我已经添加了include_once文件，如上面和更改路径和这些挂钩的罚款。

I've created a new folder off the root called 'extrapages' and I'm going to have pages in there that have information relating to the site. I've added the include_once files like above and change the path and these hook up fine.

我发现这个问题是路径中包含文件失败。例如：如果一个图像或其他包含文件中包含它从extrapages文件夹中运行时出现故障。路径问题。

The problem I'm find is paths within the include files fail. eg: if an image or another include file is within the include it fails when run from the 'extrapages' folder. Pathing issue.

有没有好的办法来处理这​​个？ 我可以改变一个偶然的机会/路径设置站点根目录（WWW）的页面下的extrapages到一个文件夹下？

Is there a good way to deal with this? Can I change/set the path to the site root (www) for pages under 'extrapages' to one folder down by chance?

我可以将这些网页上的根源，他们会运行得很好，但我真的不希望在站点的根目录所有的混乱。

I could move these pages onto the root and they would run fine but I really don't want all the clutter on the root of the site.

任何想法和放大器; THX

Any ideas & thx

推荐答案

的关键，任何路径问题被称作绝对路径

The key to any path problem is called absolute path

• 在创建的链接的为您的网站（包括图像源），总是从 / 启动其次是完全正确的路径。它永远不会让你失望。

• while creating hyperlinks for your site (including image sources), always start it from / followed by full correct path. And it never fail you.

同为文件系统调用：总是使用绝对路径。你的服务器通常为您提供了一个名为 $ _ SERVER ['DOCUMENT_ROOT'] 包含的地步，文件系统满足web服务器非常方便的变量，指向你的网站根目录。

same for the filesystem calls: always use absolute path. Your server usually provides you with very handy variable called $_SERVER['DOCUMENT_ROOT'] contains the point where filesystem meet web-server, pointing to your web root directory.

所以，从任何地方在您的网站调用的时候，

So, when called from anywhere in your site,

include $_SERVER['DOCUMENT_ROOT'].'/scripts/php/index_mainImageJoin.php';

总是指向同一位置

will point always to the same location
