What are the best practices for handling server-side and client-side interactions in PHP and JavaScript?

When handling server-side and client-side interactions in PHP and JavaScript, it is important to separate concerns and use proper communication methods. One common practice is to use AJAX requests to send data from the client-side to the server-side without reloading the page. This allows for dynamic updates and interactions without disrupting the user experience. 

// PHP code snippet for handling AJAX requests
if(isset($_POST['data'])){
   $data = $_POST['data'];
   
   // Process the data and send back a response
   echo json_encode(['message' => 'Data received successfully']);
   exit;
}
