相对路径/绝对路径 [英] relative path / absolute path
问题描述
问候：
解决文档中路径的最佳方法是什么？无论打开它的路径是什么？
路径？例如：我有x.php，它包含< img
src =" images ...">，（其中包括像php代码），它解决了这个问题。 />
在/下打开时正确的图像路径但是当x.php被读入文件时
下/ dir图像不再解析，原因很明显。使用绝对的
路径，这不是一个问题，但它是相对路径。虽然我可以想到一两块钱，我觉得有一个更优雅的解决方案。
提前谢谢。

Greetings:
What is the best way to resolve paths within a document regardless of what
path it is opened under? For example: I have x.php and it contains <img
src="images...">, (amongst other things, like php code), which resolves the
correct image path when opened under / but when x.php is read into a file
under /dir the image no longer resolves, for obvious reasons. With absolute
paths, this isn''t an issue but it is with relative paths. Although I can
think of a kludge, or two, I figure that there is a more elegant solution.
Thanks in advance.

如果我理解正确的话，这实际上是一个Web服务器问题，并且是由Apache中的别名功能处理的（其他服务器可能称之为
其他服务器）。此功能允许您设置路径前缀 - 例如，
/ images - 并将所有对图像的引用解析到同一个地方。
所以在您的代码< img src =" /images/foo.gif">并且无论在何处引用
，它都会在/my_web/images/foo.gif中解析为
。
别名也可用于css，javascript或任何其他通常
共享代码元素。
希望这会有所帮助。

If I understand you correctly, this is really a web server issue and is
handled by the ''Alias'' function in Apache (other servers may call it
something else). This function allows you to set a path prefix - say,
/images - and have all references to an image resolve to the same place.
So in your code you would have <img src="/images/foo.gif"> and it would
resolve to /my_web/images/foo.gif regardless of where it was referenced
in your web document tree.
Aliases may also be used for css, javascript or any other commonly
shared code elements.
Hope this helps.

我不明白你的问题。但是，我更喜欢相对路径和
没有问题。

I don''t understand your problem. But, I prefer relative path and
had no issues with it.

安全的一面使用绝对路径，这个肯定会工作。
为了保持你的脚本可维护，你可以制作一个配置文件，你可以把路径放进去。例如
config.php
Well to be on the safe side use absolute paths, this will definitely work.
To keep your scripts maintainable, make a configuration file where you will
put the paths in. E.g
config.php
