What is the role of AJAX in executing PHP scripts without reloading the entire page?

AJAX allows for asynchronous communication between the client-side and server-side, enabling PHP scripts to be executed without reloading the entire page. This is achieved by sending requests to the server in the background and updating only specific parts of the webpage with the response, resulting in a smoother and more dynamic user experience. 

<?php
// PHP script to handle AJAX request
if(isset($_POST['data'])){
    // Process the data received from the client-side
    $data = $_POST['data'];
    
    // Perform any necessary operations
    
    // Return a response to the client-side
    echo json_encode(['message' => 'Data processed successfully']);
}
?>
