An object is in an array and is referenced. As expected, var_dumping the array shows '&':
|
|
array(1) {
|
|
[0]=>
|
|
&object(stdClass)#%d (0) {
|
|
}
|
|
}
|
|
Naturally, this remains true if we modify the object:
|
|
array(1) {
|
|
[0]=>
|
|
&object(stdClass)#%d (1) {
|
|
["x"]=>
|
|
int(1)
|
|
}
|
|
}
|
|
|
|
|
|
Obtain the array of interfaces implemented by C.
|
|
The result is an array in which each element is an object (an instance of ReflectionClass)
|
|
Var_dumping this array shows that the elements are referenced. By what?
|
|
array(1) {
|
|
["I"]=>
|
|
&object(ReflectionClass)#%d (1) {
|
|
["name"]=>
|
|
string(1) "I"
|
|
}
|
|
}
|
|
Modify the object, and it is apparently no longer referenced.
|
|
array(1) {
|
|
["I"]=>
|
|
object(ReflectionClass)#%d (2) {
|
|
["name"]=>
|
|
string(1) "I"
|
|
["x"]=>
|
|
int(1)
|
|
}
