How do I use PHP to find a file's directory?

a10waveracer · 09-06-2005, 07:13 PM

Okay, I am making an installer for a PHP site I am helping work on, and I want the web-installer to automatically detect what the directory is that contains the installer file (ex. if the files was in /web/nuke/install.php, I want it to be able to figure out it is /nuke/ or whatever it may be).

I have tried a couple of different things, but I can never get it to just give me the directory that contains that file.

If anyone could help me with this, I would greatly appreciate it.

Thanks!

It might be useful to know what you've already tried. Do you plan for the PHP script to work on multiple webservers, or just one? For example, you can get Apache's base directory via apache_getenv and use the pathinfo function on your file, then compare the first and second strings for the answer you're looking for... there is probably an easier way to do it, but I can't see it right now.

Yes, I plan on this being used on multiple webservers hopefully, seeing as how this is a open-source project. Basically I have tried some random commands I found on the interwebs, none of them working. The only thing I could really think of doing is somehow pulling the information from the request for the file.... ex. if the url was http://www.google.com/test/install.php, is there a way I could pull out that parent directory with a command of some sort?

parse_url should be useful. You would still probably need to chop everything from the last '/' with some basic string functions though.
