There is an interface
interface TestInterface { public function test(); public function test2(); } There are several parent classes
class ParentClass1 implements TestInterface { public $child = false; public function test() { if (!$this->child) { return 'fail'; } echo 'test1'; } public function test2() { echo 'test2'; } } class ParentClass2 implements TestInterface { public $child = false; public function test() { if (!$this->child) { return 'fail'; } echo 'test2'; } public function test2() { echo 'test2'; } } And there are randomly inherited classes
class ChildClass1 extends ParentClass1 { public $child = 1; } class ChildClass2 extends ParentClass2 { public $child = 2; } The parent class itself can be created (not abstract), and the test2 method can be called. To allow the test method to be performed only for children, you have to insert this crutch into each parent class.
if (!$this->child) { return 'fail'; } In the application of course, such classes are much more than 2, you have to repeat the same crutch in many classes. There was a thought to make a general abstraction for all parent classes, implement the __call method in it, make protected methods, and catch method calls. But php swears (because the interface, which means only public). Any ideas on how to catch method calls in another way?
