How can jQuery simplify the process of handling AJAX requests in PHP compared to traditional JavaScript methods?

Handling AJAX requests in PHP using traditional JavaScript methods can be cumbersome and error-prone due to the need to manually set up XMLHttpRequest objects, handle different browser implementations, and manage the response data. jQuery simplifies this process by providing a set of AJAX methods that abstract away much of the complexity, making it easier to send and receive data from the server. 

<?php
// PHP code to handle AJAX request using jQuery

// 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
    $data = $_POST['data']; // Retrieve data sent in the AJAX request
    
    // Perform any necessary processing
    
    // Send a response back to the client
    echo json_encode(['message' => 'Request processed successfully']);
    
}else{
    // Handle non-AJAX requests here
    echo "This endpoint only accepts AJAX requests";
}
?>
