How can the correct URL address be determined when submitting a form using JavaScript in PHP?

When submitting a form using JavaScript in PHP, the correct URL address can be determined by accessing the current URL using `$_SERVER['REQUEST_URI']` and then appending it to the base URL of the website. This ensures that the form submission is directed to the correct endpoint on the server. 

$base_url = "http://www.example.com";
$current_url = $_SERVER['REQUEST_URI'];
$form_action = $base_url . $current_url;

echo "<form action='$form_action' method='post'>";
// Rest of the form code
echo "</form>";
