Get webroot in php

Question

I am using apache server for php. How can i retrieve my web root in php like http://localhost/testthesis/ help me please

Answer 1

either:

'http'.$_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];

or:

dirname(__FILE__);

on a file in the webroot, save it in a global or a registry if you want to use it in subdirs.

Answer 2

Web root is always just /
you'd never need hostname or protocol part
and root can be only root of the server, not some folder or file

if you need some path, like /testthesis/ - thre are ways, but it has nothing common with web root

if you need filesystem dir for the webroot - it's in the $_SERVER['DOCUMENT_ROOT'] variable

Answer 3

What you're looking for is not a webroot but rather a URL.

You can get your current URL like so:

$protocol = strpos($_SERVER['SERVER_SIGNATURE'], '443') !== false ? 'https://' : 'http://';
$url = $protocol . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];

Answer 4

for relative paths:

for your webservers root directory, use:

$folder = '/';

for the directory of the retrieved script, use:

$folder = './';

for absolute paths (from client's perspective):

for your webservers root directory, use:

$protocol = $_SERVER['HTTPS'] == '' ? 'http://' : 'https://';
$folder = $protocol . $_SERVER['HTTP_HOST'];

for the directory of the retrieved script, use:

$protocol = $_SERVER['HTTPS'] == '' ? 'http://' : 'https://';
$folder = $protocol . $_SERVER['HTTP_HOST'] . basename($_SERVER['REQUEST_URI']);
