You can use $_SERVER variable to get current page URL in PHP. The following example code shows how to get current full URL with query string using $_SERVER variable in PHP.

$protocol = ((!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off') || $_SERVER['SERVER_PORT'] == 443) ? "https://" "http://";

Use $_SERVER['HTTP_HOST'] to get header from the current request and $_SERVER['REQUEST_URI'] to get URI of the current page.
