How can PHP be used to dynamically generate content based on user selections in a form?

To dynamically generate content based on user selections in a form using PHP, you can use AJAX to send the form data to a PHP script, process the data in the PHP script, and then return the dynamically generated content back to the webpage.

<?php
if(isset($_POST['user_selection'])) {
    $user_selection = $_POST['user_selection'];
    
    // Process user selection and generate dynamic content
    $dynamic_content = "You selected: " . $user_selection;
    
    // Return the dynamic content
    echo $dynamic_content;
}
?>
