Description:
------------
The reproduce code is in a test format.  In php 5.1.4, it outputs the expected output, it does not in 5.2.0, or does it in the 5.2.1 snapshot from today.  It was reported to be fixed on 2007-01-10, but isn't yet.  The symfony framework depends upon this capability.

Reproduce code:
---------------
--TEST--
 Bug #39449 (Behavior changed from php 5.1.4 to 5.2.0)
--FILE--
<?php
// hacked for this test
$ns = 'test';

class ParameterHolder {
  protected $parameters = array();
  public function & get($name) {
      return & $this->parameters[$ns][$name];
  }
  public function setByRef($name, & $value) {
    if (!isset($this->parameters[$ns]))
      $this->parameters[$ns] = array();
    $this->parameters[$ns][$name] =& $value;
  }
}

class Bug39449 {
  protected
    $varHolder = null;
  public function __construct() {
    $this->varHolder = new ParameterHolder();
  }
  public function getVarHolder() {
    return $this->varHolder;
  }
  public function __set($key, $value) {
    return $this->varHolder->setByRef($key, $value);
  }
  public function __get($key) {
    return $this->varHolder->get($key);
  }
}

$b = new Bug39449();
$b->foo = Array();
$b->foo[0] = 'bar';

foreach  ($b->foo as $k => $v) {
  echo "$k => $v\n";
}
?>
--EXPECT--
0 => bar
