New Comment:
I played around with the test case a bit more and it seems that the
default RecursiveArrayIterator iterates the public properties of objects
within the arrays.
For example, if I adda public $foo = 'bar' property to the Fruit class,
I get the following (incorrect) output:
Default recursive array iteraration:
title => apple
foo => bar
title => orange
foo => bar
title => banana
foo => bar
title => grape
foo => bar
title => peach
foo => bar
title => strawberry
foo => bar
title => grapefruit
foo => bar

I tried changing the scope of the $title property from protected to
public and the test case does indeed run correctly.
Even so, the test case should still run correctly when the property is
protected.

Replace "protected" with "public" and it works fine..

This bug still exists in PHP 5.2.3 using the same test script as
before.

Description:
------------
The default implementation of hasChildren() in RecursiveArrayIterator
does not work if the recursive array contains object references. If I
subclass the RecursiveArrayIterator and re-implement the method exactly
as it is in the source code everything is fine. If I use the default
implementation, the objects in my array do not get iterated.
Inside my re-implemented hasChildren() method if I call
parent::hasChildren() it returns 1 when $this->current() is an object.
