Why does the following code
<?php
interface I {
public function a();
}
class A implements I {
public function a() {}
}
class B extends A {
}
if (is_subclass_of('A', 'I')) echo "A implements I\n";
if (is_subclass_of('B', 'I')) echo "B implements I\n";
?>
outputs:
B implements I
I would expect the following output:
A implements I
B implements I
