This check compares calls to functions or methods with their respective definitions.
If the call has less arguments than are defined, it raises an issue.
If a function is defined several times with a different number of parameters, the
check may pick up the wrong definition and report false positives. One codebase
where this has been known to happen is Wordpress. Please note the @ignore annotation hint above.

In this branch, the function will implicitly return null which is incompatible with the type-hinted return array. 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}}
