What potential pitfalls should be considered when using alert boxes in PHP for user notifications, and are there more modern alternatives?

When using alert boxes in PHP for user notifications, potential pitfalls include interrupting the user experience, being intrusive, and not being easily dismissible. A more modern alternative is to use AJAX calls to dynamically update the page content without interrupting the user flow. 

// Example of using AJAX to display notifications without alert boxes

// PHP code to handle AJAX request
if(isset($_POST['message'])) {
    $message = $_POST['message'];
    
    // Process the message and return a response
    echo json_encode(['success' => true, 'message' => $message]);
    exit;
}
```

```javascript
// JavaScript code to make AJAX request and display notification
function displayNotification(message) {
    $.ajax({
        type: 'POST',
        url: 'notification_handler.php',
        data: { message: message },
        success: function(response) {
            if(response.success) {
                // Display the message to the user in a non-intrusive way
                console.log(response.message);
            }
        },
        error: function() {
            console.log('Error displaying notification');
        }
    });
}

// Call the function with the desired message
displayNotification('This is a notification message.');
