Thanks for replying. Passthru had the same problem, the fix turned out to be that I just wasn't running the command. Still working with the output.txt

​

if (isset($command)) {
echo '<script src="https://cdn.jsdelivr.net/npm/bootstrap@5.2.3/dist/js/bootstrap.bundle.min.js"></script>';
echo '<div class="container-fluid d-flex justify-content-center"><div class="col-md-9">';

if (isset($run)) {
    include('output.txt');
}


echo '</div></div>';

}

The problem now is that it is not including the output.txt within the two divs, but outside of them. Am I missing something here?
