I found a rather strange problem with reference to objects.  Take the following:

<?php

class foo {
  var $Name;
  function foo($name) {
    $this->Name = $name;
  }
}

$bar = new foo('Mike');
$list[] =& $bar;
//unset($bar);
$bar = new foo('Jeremy');
$list[] =& $bar;

while(list($key, $val) = each($list))
  echo "<br>$key = $val->Name";

?>

When going through the loop and echoing the Name parameter the both return Jeremy.  If I unset $bar first (by uncommenting it) it works fine.  I'm not exactly sure what's going on but it is rather strange.
