What limitations does PHP have in accessing client-side information compared to JavaScript?

PHP has limitations in accessing client-side information compared to JavaScript because PHP is a server-side language, meaning it runs on the server and cannot directly interact with client-side elements like the browser window or user input. To overcome this limitation, you can use JavaScript to capture client-side information and send it to the server using AJAX requests. 

// PHP code to receive client-side information sent via AJAX
$data = json_decode(file_get_contents('php://input'), true);

// Access the client-side information sent from JavaScript
$clientData = $data['clientData'];

// Process the client-side information in PHP
// Your code here to handle the clientData
