REST API Client Examples

Greetings,
Are there any complete PHP cURL examples available that demonstrate best practices for securely accessing SQL databases that have been enabled with REST APIs via PHP Runner's "REST API" button on the Miscellaneous panel?

I installed the latest 10.5 Enterprise build but the Help still references 10.4, was wondering if the 10.5 Help might include more detailed examples or if anyone can provide additional info.

Thanks!
