If you access a property on an interface, you most likely code against a concrete implementation of the interface.
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; }
