<?

class Item
{
 function Foo()
 {
  echo "calling Item::Foo\n";
 }
}

class Container
{
 var $item;

 function Container()
 {
  $this->item = new Item();
 }

 function callFoo()
 {
  $this->item->Foo();
 }

$c = new Container();

echo "<xmp>\nBEFORE:";
var_dump($c);

$c->callFoo();

echo "\nAFTER:";
var_dump($c);
echo "</xmp>";

BEFORE:
object(container)(1) {
  ["item"]=>
  object(item)(0) {
  }
}
calling Item::Foo

AFTER:
object(container)(1) {
  ["item"]=>
  &object(item)(0) {
  }
}
