'=&' makes a reference (in C known as pointer) to a data object in memory.
This way you don't duplicate the memory but share the same memory to prevent resource increase.

In case of a Object like

PHP Code:


			
<?php

$ref =& new Object();

you are working on the base object and NOT a instance.
So if you create an object like this and create another instance, you actualy get all the values of $ref.
