What client-side technologies like AJAX or Websockets could be used to achieve a page reload for all users?

To achieve a page reload for all users without requiring them to manually refresh the page, we can utilize client-side technologies like AJAX or Websockets. With AJAX, we can make asynchronous requests to the server to check for updates and reload the page accordingly. Websockets provide a persistent connection between the client and server, allowing real-time communication for triggering a page reload. 

```php
<!-- HTML code to include jQuery library -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>

<!-- JavaScript code using AJAX to reload the page for all users -->
<script>
$(document).ready(function(){
    setInterval(function(){
        $.ajax({
            url: 'reload.php',
            success: function(data){
                location.reload();
            }
        });
    }, 5000); // Reload the page every 5 seconds
});
</script>
```

In the above code snippet, we use jQuery to make an AJAX request to a PHP script named `reload.php` every 5 seconds. Inside the PHP script, you can implement the necessary logic to trigger a page reload. This approach ensures that all users will have their pages automatically refreshed without manual intervention.
