How can PHP developers avoid errors related to interface implementation in inheritance?
To avoid errors related to interface implementation in inheritance, PHP developers should ensure that all methods defined in the interface are implemented in the child class that is inheriting from the parent class. This includes matching the method signatures exactly, including parameter types and return types.
interface MyInterface {
public function myMethod(): void;
}
class ParentClass implements MyInterface {
public function myMethod(): void {
// implementation
}
}
class ChildClass extends ParentClass {
// Ensure that myMethod is implemented here
}
