Are there best practices for updating output in PHP without using JavaScript?

When updating output in PHP without using JavaScript, one common approach is to use AJAX requests to send data to a PHP script that processes the data and returns updated content. This can be achieved by creating a separate PHP file to handle the AJAX request and update the output accordingly. 

```php
<?php
if(isset($_POST['data'])) {
    // Process the data sent via AJAX request
    $data = $_POST['data'];
    
    // Update output based on the processed data
    echo "Updated output: " . $data;
}
?>
```

In this code snippet, we check if there is data sent via POST request, process the data, and then update the output accordingly. This allows for updating output in PHP without relying on JavaScript for dynamic content updates.
