User-friendly path/url determining class?

schwim

Hi there guys,

A while ago, you all helped me with some snippets that would try to guess a script's path and URL to help a person installing a script determine where the script location is, so it could save it to a config file. Since then, I've noticed while dealing with a lot of scripts that there must be some foolproof method of doing this because the scripts that I install don't even ask me. Wordpress for instance touts a three step install and other than db info, they don't ask you for any path of URL info.

In your opinion, is this because the script is using relative paths for everything or is there a(n almost) foolproof method of determing this so it doesn't require user assistance? I'd love to be able to skip this part of my install process on scripts.

Thanks for any thoughts you might have,

Perhaps this is what you're looking for, from $SERVER:
The filename of the currently executing script, relative to the document root. For instance, $SERVER['PHP_SELF'] in a script at the address http://example.com/test.php/foo.bar would be /test.php/foo.bar. The FILE constant contains the full path and filename of the current (i.e. included) file. If PHP is running as a command-line processor this variable contains the script name since PHP 4.3.0. Previously it was not available.

Hi there johan, and thanks very much for your response.

I'm trying to find the method through Wordpress, but to be honest, the complexity of the code makes it a little tough.

Here's the snippet I'm currently using for path & URL, but I receive mixed reports of success from users of the script:

$autopath = dirname(dirname(__FILE__));
$autourl = dirname(dirname('http://' . $_SERVER['SERVER_NAME'] . $_SERVER['PHP_SELF']));

This script is of course moving up a directory, which explains the extra dirname.

I was just wondering if there was a better method than this of determining path and URL.

Thanks very much again for your response.

thanks,

I'm not sure what you're trying to accomplish. Let's assume that your webroot is /home/data/www/ and that the script is in /home/data/www/php/file.php

$autopath would be /home/data/www
$autourl would be http://yourdomain.com

That seems ok, even though I don't know why you'd want to get the directory above the used file.

However, if the file is in the webroot, you'd get
/home/data
http:

Moreover, if the webroot directory is in / then you actually get a / not an empty string.
