How can the display location of a link to a protected area be controlled in PHP forms?

To control the display location of a link to a protected area in PHP forms, you can use conditional statements to determine when and where the link should be displayed based on the user's authentication status. This can be done by checking if the user is logged in or has the necessary permissions before rendering the link in the form.

<?php
session_start();

// Check if user is logged in or has necessary permissions
if(isset($_SESSION['logged_in']) && $_SESSION['logged_in'] == true) {
    // Display link to protected area
    echo '<a href="protected_area.php">Go to Protected Area</a>';
}
?>
