Are there any best practices for placing a button in a PDF that triggers a PHP command?

Placing a button in a PDF that triggers a PHP command can be achieved by using an interactive form element in the PDF file. The button can be set up to submit the form data to a PHP script when clicked. The PHP script can then process the data and perform the desired action. 

```php
<?php
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    // Process the form data here
    // For example, save the data to a database
    // Or perform any other necessary action
    // You can access the form data using $_POST array
}
?>
```

This code snippet demonstrates a basic PHP script that can be used to process the form data submitted from a PDF button. You can customize the script to suit your specific requirements and perform the necessary actions based on the form data received.
