What potential issues can arise when trying to display server status on a website using PHP?

One potential issue that can arise when trying to display server status on a website using PHP is the server being unresponsive or slow, which can lead to delays in retrieving and displaying the status information. To solve this, you can implement asynchronous requests using AJAX to fetch the server status data without blocking the page load. 

```php
<!DOCTYPE html>
<html>
<head>
    <title>Server Status</title>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
</head>
<body>
    <div id="server-status"></div>

    <script>
        $(document).ready(function(){
            $.ajax({
                url: 'server_status.php',
                type: 'GET',
                success: function(response){
                    $('#server-status').html(response);
                },
                error: function(){
                    $('#server-status').html('Error retrieving server status.');
                }
            });
        });
    </script>
</body>
</html>
```

In this code snippet, we use jQuery to make an AJAX request to a PHP file called `server_status.php` to fetch the server status data asynchronously. The response from the PHP file is then displayed in a `div` with the id `server-status`. If there is an error retrieving the server status, an error message is displayed instead.
