s there any difference between print and echo in PHP? If so, which should I use and when? If not, why are there two keywords?

UPDATE :

At the downvoters : please read the SO faq. SO was setup also to capture googleable questions. so you shouldn't downvote for that, this question is a valid question, answered on a lot of places and now on SO too.

Of course you can downvote for another reason, but please leave a comment in the lines of -1 : downvoted for .. , cause for now, I'm not understanding the downvotes.
