Are there any specific best practices for handling cookies and header functions in PHP to avoid the need for page reloads?

To avoid the need for page reloads when handling cookies and header functions in PHP, you can use AJAX requests to send data to the server and update the page content dynamically. This allows you to set cookies and headers without refreshing the entire page. 

<?php
// Check if the request is an AJAX request
if(!empty($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest') {
    // Set cookie
    setcookie('cookie_name', 'cookie_value', time() + 3600, '/');
    
    // Set header
    header('Content-Type: application/json');
    
    // Return JSON response
    echo json_encode(['message' => 'Cookie and header set successfully']);
    exit;
}
?>
