How can PHP be used to protect specific parts of a webpage instead of the entire page?

To protect specific parts of a webpage using PHP, you can use conditional statements to check if a user is authenticated before displaying the protected content. This can be achieved by setting up a login system and storing user authentication status in a session variable. Then, use PHP to check this session variable before rendering the protected content on the webpage. 

<?php
session_start();

if(isset($_SESSION['authenticated']) && $_SESSION['authenticated'] === true) {
    // Display protected content here
    echo "Welcome, authenticated user!";
} else {
    // Display login form or redirect to login page
    echo "Please login to access this content.";
}
?>
