dcc php examlpe: Undefined variable: jsonArrayResponse

[philharmonie]

The variable $jsonArrayResponse is defined in the code, but not available in this context.

Same for $hasResult in #624.

Even the returned function searchTests() does not exist at all.

With that, the code is not working at all.
