Using exit here is not recommended.

In general, usage of exit should be done with care and only when running in a scripting context like a CLI script.

Bug Best Practice introduced by
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
    }
