What are the best practices for integrating PHP code execution with client-side events in web development?

When integrating PHP code execution with client-side events in web development, it is important to use AJAX to send requests to the server without reloading the entire page. This allows for dynamic content updates based on user interactions. Additionally, using event listeners in JavaScript to trigger the AJAX requests based on specific client-side events can enhance the user experience. 

<?php
// PHP code to handle AJAX request
if(isset($_POST['data'])){
    $data = $_POST['data'];
    
    // Process the data and return a response
    echo "Data received: " . $data;
}
?>
