Question

I\'d like to find the base url of my application, so I can automatically reference other files in my application tree...

So given a file config.php in the base of my

Answer 1

url root of the application can be found by

$protocol = (strstr('https',$_SERVER['SERVER_PROTOCOL']) === false)?'http':'https';
$url = $protocol.'://'.$_SERVER['SERVER_NAME'].dirname($_SERVER['REQUEST_URI']);

this code will return url path of any application whether be online or on offline server.

I've not made proper check for proper '/'. Please modify it for slashes.

this file should be placed in root.

example : if application url :

http://localhost/test/test/test.php

then this code will return

http://localhost/test/test
