Question

PHP : Document root directory backslash problem.

Answer 1

A:

For using local files from the browser, use the file scheme.

file://C:/dir/file.ext
file:///dir/file.ext

Not sure if you need two or three slashes, probably two on windows with the drive letter, three on *nix with the root slash, though I seem to recall seeing three slashes with the drive letter. Try it! :P

Answer 2

+8 A:

Just use this:

<head>
    <link href='/include/style.css' rel='stylesheet' type='text/css' />
    <title>eLMS</title>
</head>

Or, if it is used locally:

<head>
    <link href='../include/style.css' rel='stylesheet' type='text/css' />
    <title>eLMS</title>
</head>

The document root is for internal usage (inside of PHP) only, not for in your HTML.

Note that `'include/style.css'` is also a relative url to the subdirectory include from the current directory.

I need to use absolute paths. This saves me the trouble of putting an 'include' folder in every subdirectory of the project, no?

wretrOvian 2010-01-06 19:16:34

You can go back a number of folders by adding more ../.. (The directory where you put your css includes MUST be available from the document root, you can't put it below it.

Jimmy Shelter 2010-01-06 19:18:06

@wretrOvian: Technically, the first url is absolute. To clarify, the webserver's `/` uri is the file system's `$_SERVER['DOCUMENT_ROOT']`.

R. Bemrose 2010-01-06 19:20:35

@Bemrose: Agreed, but this is an isolated case. I highlight again that if i'm in a deep subdirectory - i will have to modify the code for every page - AND if my header links to the stylesheet - i'll have to use a custom header for every subdirectory.

wretrOvian 2010-01-06 19:21:48

@wretrOvian: `$_SERVER['DOCUMENT_ROOT']` does not change when you go into deeper subdirectories. It's still whatever you set the document root to in your web server's configuration.

R. Bemrose 2010-01-06 19:23:38

By using just /include, you should be able to access the include directory from every other subdirectory.

Jimmy Shelter 2010-01-06 19:25:08

@wretrOvian: His first suggestion is to use `/include/style.css` which will always map to `C:\Users\wretrOvian\Documents\eLMS\site\include\style.css` If you want a relative root directory in a url, you need to use `./`

R. Bemrose 2010-01-06 19:27:14

@Bemrose: From any sub-subdirectory whatsoever, are you sure? :/

wretrOvian 2010-01-06 19:28:18

@Bemrose, @Jimmy: Got it. Thanks :]

wretrOvian 2010-01-06 19:29:59

Yes; root-relative paths are absolute. And are consistent through the entire site (since they're relative to the web-root, which doesn't change).

Answer 3

A:

Try using the DIRECTORY_SEPARATOR constant. It returns \ on Windows systems and / on *nix systems.

Answer 4

A:

Try using:

$_SERVER['HTTP_HOST']

Answer 5

A:

First of all, the document root is literally the directory that the web server's / is located at. You do not usually want to use this with any content on the web. Use / instead.

R. Bemrose 2010-01-06 19:13:31

Answer 6

+1 A:

Don't use a filesystem absolute path, use a path relative to (but not including) the document root. In this case just /include/style.css.
