function &getItem($name)
{
return $this->items[$name];
}
}
$obj = new simple();
print "Keys before getting item:\n".print_r(array_keys($obj->items),
TRUE)."\n";
$retrieved =& $obj->getItem('SHOULD_NOT_EXIST');
print "Retrieved: \n";
var_dump($retrieved);
print "Keys after getting item:\n".print_r(array_keys($obj->items),
TRUE)."\n";
