33--EXPECTF--
34An object is in an array and is referenced. As expected, var_dumping the array shows '&':
35array(1) {
36  [0]=>
37  &object(stdClass)#%d (0) {
38  }
39}
40Naturally, this remains true if we modify the object:
41array(1) {
42  [0]=>
43  &object(stdClass)#%d (1) {
44    ["x"]=>
45    int(1)
46  }
47}
48
49
50Obtain the array of interfaces implemented by C.
51The result is an array in which each element is an object (an instance of ReflectionClass)
52Var_dumping this array shows that the elements are referenced. By what?
53array(1) {
54  ["I"]=>
55  object(ReflectionClass)#%d (1) {
56    ["name"]=>
57    string(1) "I"
58  }
59}
60Modify the object, and it is apparently no longer referenced.
61array(1) {
62  ["I"]=>
63  object(ReflectionClass)#%d (2) {
64    ["name"]=>
65    string(1) "I"
66    ["x"]=>
67    int(1)
68  }
69}
