' =& $var' seems to be equal to '= &$var'. It is used in the 
documentation example in:
http://www.php.net/manual/en/language.references.arent.php
http://www.php.net/manual/en/language.references.spot.php

Also not completely true. Object variables don't contain the actual 
object as value, but contain an identifier which allows PHP to find the 
actual object. If you pass, return or assign an object to another 
variable the identifier is copied.
References are aliases of the same variable.
