<excerpt cite="http://www.zend.com/php5/andi-book-excerpt.php";>
In PHP 5, the infrastructure of the object model was rewritten to work 
with object handles. Unless you explicitly clone an object by using the 
clone  keyword you will never create behind the scene duplicates of 
your objects. In PHP 5, there is neither a need to pass objects by 
reference nor assigning them by reference. </excerpt>
