			0 ignored issues – show Bug Best Practice introduced 2019-12-22 00:59 UTC by Report Bug Copy Issue Report 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: interface ReturnsInt { public function returnsIntHinted(): int; } class MyClass implements ReturnsInt { public function returnsIntHinted(): int { if (foo()) { return 123; } // here: null is implicitly returned } } Loading history...
