PHP object1==object2 is Java object1.equals(object2), but the PHP class 
can not override the functionality it is always all fields

PHP object1===object2 is Java object1==object2

PHP simple1===simple2 is Java simple1==simple2

PHP simple1==simple2 does not have a Java equivalent as PHP is doing 
various type conversions to see if it is logical the same
