$f initially points to the first object:
|
|
object(Inc)#%d (1) {
|
|
["id"]=>
|
|
int(1)
|
|
}
|
|
Assigning new object directly to $k affects $f:
|
|
object(Inc)#%d (1) {
|
|
["id"]=>
|
|
int(2)
|
|
}
|
|
Assigning new object by ref to $k removes it from $f's reference set, so $f is unchanged:
|
|
object(Inc)#%d (1) {
|
|
["id"]=>
|
|
int(2)
|
|
}
