Description:
------------
I'm using an array of objects and when I copy the array to an another array structure this will referencing, not copying.
I tried to use copy() statement, but it works only to objects, off-course.
Soorry by bad english.

Reproduce code:
---------------
class slaveObject {
  public $singleVar;
  public __construct($mySingleVar) { $this->sigleVar = $mySingleVar; }
}
class mainObject {
  public $objects = array();
  public __construct() {
    $this->objects[] = new slaveObject('Example1');
    $this->objects[] = new slaveObject('Example2');
    $this->objects[] = new slaveObject('Example3');
  }
}

$myObject = &new mainObject();
$myObjectArray = $myObject->objects;
print_r($myObject->objects);
$myObjectArray[0]->singleVar = 'Example4';
print_r($myObject->objects);
print_r($myObjectArray);

Expected result:
----------------
Array(
  [0] => slaveObject (
    [singleVar] => Example1
  )
  [1] => slaveObject (
    [singleVar] => Example2
  )
  [2] => slaveObject (
    [singleVar] => Example3
  )
)
Array(
  [0] => slaveObject (
    [singleVar] => Example1
  )
  [1] => slaveObject (
    [singleVar] => Example2
  )
  [2] => slaveObject (
    [singleVar] => Example3
  )
)
Array(
  [0] => slaveObject (
    [singleVar] => Example4
  )
  [1] => slaveObject (
    [singleVar] => Example2
  )
  [2] => slaveObject (
    [singleVar] => Example3
  )
)

Actual result:
--------------
Array(
  [0] => slaveObject (
    [singleVar] => Example1
  )
  [1] => slaveObject (
    [singleVar] => Example2
  )
  [2] => slaveObject (
    [singleVar] => Example3
  )
)
Array(
  [0] => slaveObject (
    [singleVar] => Example4
  )
  [1] => slaveObject (
    [singleVar] => Example2
  )
  [2] => slaveObject (
    [singleVar] => Example3
  )
)
Array(
  [0] => slaveObject (
    [singleVar] => Example4
  )
  [1] => slaveObject (
    [singleVar] => Example2
  )
  [2] => slaveObject (
    [singleVar] => Example3
  )
)
