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/?

Answer 1

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'];
