It should maybe point the reader to class_implements() for a way to realiable check that a class name (string) implements a given interface. Test script: --------------- <?php interface MyInterface {} class MyClass implements MyInterface {} // This will fail on 5.3.8 and earlier, this has been fixed // in #53727, but doc does not reflect that. echo (is_subclass_of('MyClass', 'MyInterface') ? 'true' : 'false'); Expected result: ---------------- true Actual result: -------------- false ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=62969&edit=1
