What are the limitations of using PHP for real-time updates on a webpage?

One limitation of using PHP for real-time updates on a webpage is that PHP is a server-side language, meaning it cannot update content on a webpage without a page refresh. To overcome this limitation, you can use AJAX (Asynchronous JavaScript and XML) to make asynchronous requests to the server and update specific parts of the webpage without reloading the entire page. 

<?php
// PHP code to handle AJAX request
if(isset($_POST['data'])){
  // Process the data and return the updated content
  $data = $_POST['data'];
  // Perform necessary operations
  echo $updatedContent;
}
?>
