Include/require effectively put the contents of the requested file(s) in the
program flow; so here is roughly what is happening based on the code you
show above:
index.php:
<!DOCTYPE HTML>
<html>
Hello World<br>
>
<?php
session_start();
//include('../../cgi-bin2/hello.php');
//require_once('db.php');
$username="user";
$password="pass";
$database="test";
$host="localhost";
echo "hello from ".$username." db.php<br>";
echo "hello from ".$username." bottom<br>";
$username="Alex";
echo "hello " . $username . " from top<br>";
?>
from html
</html>
