note 61849 added to language.references.pass

I'm still new to PHP so please bear with me.  I have two
simple classes:

class Foo {

	private $Bars;  // an array of Bar objects

	function Foo() {
		$this->Bars = array();
	}

	function addBar( &$bar ) {
		array_push( $this->Bars, $bar );
	}

	function toString() {
		while ( $bar = each( $this->Bars) ) {

			echo $bar->toString() // this generates an error

		}

	}

}

class Bar {

	function toString() {
		return "Test";
	}

}

$foo = new Foo();
$foo->addBar( new Bar() );
$foo->toString();

Which generates the following error:

Fatal error: Call to a member function toString() on a
non-object in test.php

Can any of you PHP gurus point me to what I'm doing wrong?
