动态图像SRC [英] Dynamic Image SRC

问题描述

我想在我的标题和导航中使用include，并且

因为后续文件可能在不同的目录中，我想

使用动态相对链接对于图像，有点像：


< img src ="<？ $ root？> /images/foo.gif" />


我想最简单的事情就是使用绝对链接，但

是否有办法设置它，所以我可以改为PHP ？


TIA

I would like to use an include for my header and navigation, and
because subsequent files may be in different directories, I want to
use a dynamic relative link for the images, sort of like:

<img src="<? $root ?>/images/foo.gif" />

I suppose the easiest thing to do is just use absolute links, but
is there a way to set this up so I can PHP instead?

你好，Ian，


问题是：PHP如何知道哪条路径（相对或绝对路径）
应该添加
？

如果你能清楚地描述它，你可以编程PHP来做它。

我很确定。


但是你没有向我们提供任何有用的信息，所以我不确定你期望什么样的回答

。

至于语法：没关系，只要

Hi Ian,

The question is this: How can PHP know which path (relative or absolute)
should be added?
If you can describe it clearly, you can program PHP to do it.
