Hello,
The trial package is based on the Basic package. You can read about it on the download package:
https://www.phpdocx.com/download_trial
The same license allows to use the library on the purchased subdomain (Basic), domain and its subdomains (Advanced and Premium) or IP (Premium), localhost and private networks (classes A, B and C.
If your test server uses a public IP or domain, as you are using an Advanced license we recommend you to use a test subdomain of the purchased domain.
Regards.
