What are the limitations of PHP in terms of manipulating browser content compared to JavaScript?

PHP has limitations in terms of manipulating browser content compared to JavaScript because PHP is a server-side language, meaning it runs on the server before the page is sent to the browser. This restricts PHP from directly interacting with the browser in real-time. To overcome this limitation, you can use AJAX (Asynchronous JavaScript and XML) to make asynchronous requests to the server and update the browser content dynamically without refreshing the page. 

<?php
// PHP code to handle AJAX request
if(isset($_POST['data'])){
  $data = $_POST['data'];
  
  // Perform necessary operations with the data
  
  // Send response back to the browser
  echo json_encode(['result' => 'success']);
}
?>
