title: is there any significance of using ::(scope resolution operator) with an object to access class variables?
body: <p>Although it is <strong>allowed</strong> to access class variables using the syntax:- <strong><em>$object::$variable</em></strong>, does it hold any significance i.e. in case of accessing class variables we can use either the <strong>classname or an object</strong> of that class to access a class variable isn't it?</p>
