What are the potential pitfalls of relying on PHP for real-time browser detection?

One potential pitfall of relying on PHP for real-time browser detection is that PHP is a server-side language, meaning it cannot detect changes in the user's browser without a page refresh. To solve this issue, you can use a combination of PHP and JavaScript to detect the user's browser on the client side and send the information back to the server for processing. 

// PHP code to handle browser detection on the server side
if(isset($_POST['userAgent'])) {
    $userAgent = $_POST['userAgent'];
    // Process the user agent information here
}

// JavaScript code to detect the user's browser on the client side
<script>
    var userAgent = navigator.userAgent;
    // Send the user agent information to the server using AJAX
    $.ajax({
        type: 'POST',
        url: 'browser_detection.php',
        data: {userAgent: userAgent},
        success: function(response) {
            // Handle the server response here
        }
    });
</script>
