What are some best practices for updating output dynamically in PHP without bloating the code?

When updating output dynamically in PHP, it's important to avoid bloating the code with unnecessary logic or repeated code. One way to achieve this is by using AJAX to asynchronously update the content on the page without having to reload the entire page. This can help improve the user experience and make the code more efficient. 

<?php
// Sample PHP code snippet for dynamically updating output using AJAX

// Check if the request is an AJAX request
if(isset($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest') {
    // Process the AJAX request and update the output dynamically
    $data = $_POST['data']; // Get data from the AJAX request
    // Perform necessary operations with the data
    echo $updatedOutput; // Send back the updated output
    exit; // Stop further execution
}
?>
