passing an object reference

[praveenhotha]

Can anyone please explain the following code snippet. I was expecting the output to be 0,1,2,3,4 ?? ???

<?

  class AnyClass

      {

        public $member;

        public function __construct($val)

      {

            $this->member = $val;

      }

    }

   

    $manyObjects = array();

    $obj = null;

   

    for($i = 0; $i < 5;$i++) {

        $obj = new AnyClass($i); // create new instance

        $manyObjects[] = &$obj;

   

    }

   

    for($i = 0; $i < 5;$i++) {

        echo "<br>Value:".$manyObjects[$i]->member."\r\n";

    }

   

?>

 

Output : 4

            4

            4

            4

            4

Error with :

$manyObjects[] = &$obj;

 

Should be

$manyObjects[] = $obj;

It doesn't throw any error, but prints five 4s.
