How can jQuery be integrated into a PHP script to achieve continuous and efficient webpage updates?

To achieve continuous and efficient webpage updates using jQuery in a PHP script, you can use AJAX to send requests to the server and update specific parts of the webpage without refreshing the entire page. This allows for dynamic content updates without interrupting the user experience.

<?php
// PHP script to handle AJAX requests and return updated content

// Check if AJAX request is being made
if(isset($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest') {
    // Process the AJAX request
    // Update content dynamically and return the updated data
    echo json_encode($updatedData);
    exit;
}
?>
