How can the issue of having more Exception types in sub-classes than in their parent classes be resolved in PHP?

Issue: When a subclass introduces more Exception types than its parent class, it can lead to inconsistency and confusion in handling exceptions. To resolve this issue, we can create a custom exception class in the parent class that can handle all possible exceptions thrown by both the parent and subclass. 

class ParentException extends Exception {}

class ParentClass {
    public function someMethod() {
        throw new ParentException("An error occurred in ParentClass");
    }
}

class SubClass extends ParentClass {
    public function someMethod() {
        try {
            // Code that may throw exceptions
        } catch (Exception $e) {
            throw new ParentException($e->getMessage());
        }
    }
}
