@don-leesuccessrocket-io,
The example seems to be working fine, please try changing username, password and database name accordingly. You can also download PHP Samples from our download page which you can try running locally in your machine.
If this doesn’t help you out, kindly create a sample project along with sample database reproducing the issue you are facing and share it over Google-Drive or Onedrive so that we can look into your code, understand the issue you are facing and help you out.
