How about adding an `instanceof` check? If you access a property on an interface, you most likely code against a concrete implementation of the interface. Available Fixes Adding an additional type check: interface SomeInterface { } class SomeClass implements SomeInterface { public $a; } function someFunction(SomeInterface $object) { if ($object instanceof SomeClass) { $a = $object->a; } } Changing the type hint: interface SomeInterface { } class SomeClass implements SomeInterface { public $a; } function someFunction(SomeClass $object) { $a = $object->a; } Loading history...
