Hello,
The classic package has the same folder structure than the trial package, with new classes. So if you had the trial package working, this classic package must work in the same way.
Anyway, to use phpdocx with Laravel and other NS frameworks such as Symfony or Yii, we recommend using the namespaces package available in Advanced and Premium licenses.
Please check this information about how to use phpdocx with Laravel:
https://www.phpdocx.com/documentation/cookbook/integrate-phpdocx-with-laravel
It's fully tested.
Regards.
