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}}

public function uriToTmpPicture(string $uri): Picture
It seems like $ph can also be of type false; however, parameter $handle of fwrite() does only seem to accept resource, maybe add an additional type check?

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