Question

i created a simple spaghetti code, wherein a user inputs data, then shall receive an email..my question is, how to include the url of the portal without having to hardcode it such as

http://www.test.com/index.php?activate=$test

that is, http://www.test.com <– this is all i want

is there a built-in function that i can use in order to be able to use the url of the portal and send the correct path to the recipient ?

Take a look at $_SERVER global variable and its keys.

<?php
    if ($_SERVER['HTTPS']) {
        echo 'https://' . $_SERVER['SERVER_NAME'];
    } else {
        echo 'http://' . $_SERVER['SERVER_NAME'];
    }
?>

$_SERVER is an array containing information such as headers, paths, and script locations. The entries in this array are created by the web server. There is no guarantee that every web server will provide any of these; servers may omit some, or provide others not listed here. That said, a large number of these variables are accounted for in the CGI/1.1 specification, so you should be able to expect those.
