How can I get the “application root” of my URL from PHP?

Question

If my URL is http://www.server.com/myapp/stuff/to/see and my directory structure on disk is htdocs/myapp/*, how can I extract the /myapp

Answer 1

Try this:

 echo dirname(__FILE__);

where __FILE__ is the name of current executing script, and dirname gets folder/application folder out of it.

More Options:

echo $_SERVER['DOCUMENT_ROOT']; // gives you the root dir

On PHP.net
