In this branch, the function will implicitly return null which is incompatible with the type-hinted return boolean. Consider adding a return statement or allowing null as return value.
For hinted functions/methods where all return statements with the correct type are only reachable via conditions, ?null? gets implicitly returned which may be incompatible with the hinted type.
Let?s take a look at an example:
interfaceReturnsInt{publicfunctionreturnsIntHinted():int;}classMyClassimplementsReturnsInt{publicfunctionreturnsIntHinted():int{if(foo()){return123;}// here: null is implicitly returned}}
It seems like internalException() must be provided by classes using this trait. How about adding it as abstract method to this trait?

If this is a false-positive, you can also ignore this issue in your code via the ignore-call annotation

The property internalFunctionIsCallable does not exist. Although not strictly required by PHP, it is generally a best practice to declare properties explicitly.
