It seems like $ch can also be of type false; however, parameter $ch of curl_setopt() does only seem to accept resource, maybe add an additional type check?

The constant ENVIRONMENT was not found. Maybe you did not declare it correctly or list all dependencies?

It seems like you are loosely comparing $body of type null|string against null; this is ambiguous if the string can be empty. Consider using a strict comparison !== instead.
