Find htdocs path, no matter where file is stored

Question

How can I find my htdocs directory.

When I execute the following command:

echo  dirname(__FILE__);

I get the following output:

/var/www/myexample.com/htdocs/required/css

I want to find path till /htdocs, but I don't want to hard-code the things

I know I can use:

dirname(dirname(dirname(__FILE__)))

But, that will work if the current file is in "css" directory. If I will move to some other directory inside "css" directory, then it will not work.

Any solution for this?

Answer 1

If you are running Apache, the

$_SERVER["DOCUMENT_ROOT"]

environment variable should give you the current document root. See $_SERVER in the manual.

Answer 2

On most setups $_SERVER['DOCUMENT_ROOT'] should give you what you want.
