Description:
------------
When trying to enforce arguments on constructors, PHP behaves
unexpectedly. If you define the constructor as an abstract method in a
parent level class, the __construct method argument datatype/count
checks go out the window in children. This issue is the same whether its
in an interface or abstract class.
Reproduce code:
---------------
class ExampleClass {}
interface TestInterface {
public function __construct(ExampleClass $var);
}
class Test implements TestInterface {
public function __construct() {} // NO ERROR (unexpected)
}
Expected result:
----------------
Should produce an error
Actual result:
--------------
No error is reported.
