Finally, a good and simple answer! Indeed, I have had such trouble googling "::". I don't know why, but something about giving Google a bunch of symbols doesn't give very good search results. Thanks for answering this question, it will come in very handy now that I know what the darn thing is and how to use it! I've actually asked people before, but when I ask about "that double colon thingy" I either got blank stares, or some over-technical jabbering that I could not understand. Thanks for the great post!

For a function, you'd need something like: public static function showAge(){...} then you could access it like: ClassName::showAge(); When you're working with an instance of an object, you use ->. In general, you'll get the same results since you're mostly working with Constants and static functions and they don't usually change. Check out the link in the article above for a more details. Cheers! Byron Hi beanluc,

Under what circumstancces do you use "::" but NOT "->"? Under what circumstances will either one of them work? With ot without the same result? Does it do something that “->” doesn’t do?

Under what circumstancces do you use “::” but NOT “->”?

Under what circumstances will either one of them work? With ot without the same result?
