How can PHP be used to dynamically generate text formatting in a textarea based on user input?

To dynamically generate text formatting in a textarea based on user input, you can use JavaScript to detect the input changes and send them to a PHP script for processing. The PHP script can then apply the desired formatting to the text and send it back to the client-side for display. 

<?php
if(isset($_POST['user_input'])){
    $formatted_text = '<b>' . $_POST['user_input'] . '</b>'; // Example: Wrap input in <b> tags for bold formatting
    echo $formatted_text;
}
?>
