php - Modal do not want to open - Bootstrap

one text

Solution:

You are not loading Bootstrap's javascript files, simply add:

 <script src="https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/js/bootstrap.bundle.min.js" integrity="sha384-MrcW6ZMFYlzcLA8Nl+NtUVF0sA7MsXsP1UyJoMp4YLEuNSfAP+JcXn/tWtIaxVXM" crossorigin="anonymous"></script>

To the head of your document and the modal works.
