Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

All elements of $this->array_of_object[]  point to the same object. You
have to use independent instances or clone the objects ...

Description:
------------
When a member of a class(let's say class A)is an array of objects from
other class B (who has a member that is an array too) and i want to
populate the $this->member from the class A using
$this->member[]=$some_object_of_class_b it does increase the number of
elements in the array BUT IT OVERWRITES ALL ELEMENTS VALUE OF THE
$this->member ARRAY.

Reproduce code:
---------------
class A{
  public $arry = array();
  public function set_array($array){
    $this->arry = $array;} 
}
class B{
  public $array_of_object;
  public function add_object($object){
    $this->array_of_object[] = $object;
  }
}
$array = array('I' => 'you');
$a = new A();
$b = new B();
for($i=0 ; $i < 3 ; $i++){
      $array1 = array($i=>'he'); 
      $array = array_merge($array, $array1);
      $a->set_array($array);      
      $b->add_object($a);}
var_dump($b);

Expected result:
----------------
object(B)#2 (1) {
  ["array_of_object"]=>
  array(3) {
    [0]=>
    object(A)#1 (1) {
      ["arry"]=>
      array(2) {
        ["I"]=>
        string(3) "you"
        [0]=>
        string(2) "he"
      }
    }
    [1]=>
    object(A)#1 (1) {
      ["arry"]=>
      array(3) {
        ["I"]=>
        string(3) "you"
        [0]=>
        string(2) "he"
        [1]=>
        string(2) "he"
      }
    }
    [2]=>
    object(A)#1 (1) {
      ["arry"]=>
      array(4) {
        ["I"]=>
        string(3) "you"
        [0]=>
        string(2) "he"
        [1]=>
        string(2) "he"
        [2]=>
        string(2) "he"
      }
    }
  }
}


Actual result:
--------------
object(B)#2 (1) {
  ["array_of_object"]=>
  array(3) {
    [0]=>
    object(A)#1 (1) {
      ["arry"]=>
      array(4) {
        ["I"]=>
        string(3) "you"
        [0]=>
        string(2) "he"
        [1]=>
        string(2) "he"
        [2]=>
        string(2) "he"
      }
    }
    [1]=>
    object(A)#1 (1) {
      ["arry"]=>
      array(4) {
        ["I"]=>
        string(3) "you"
        [0]=>
        string(2) "he"
        [1]=>
        string(2) "he"
        [2]=>
        string(2) "he"
      }
    }
    [2]=>
    object(A)#1 (1) {
      ["arry"]=>
      array(4) {
        ["I"]=>
        string(3) "you"
        [0]=>
        string(2) "he"
        [1]=>
        string(2) "he"
        [2]=>
        string(2) "he"
      }
    }
  }
}
