foo!!??!?!

what is foo?
and why is it always used in beginners tutorials for almost all programming langauges?

<?php
    class foo {
        function foo_me()
            $foo1 = "whats a foo?"; //php
        }
    }
    $foofoo = new foo;
    $foofoo->foo_me;
?>

fully object oriented? (It's a guess)

Which is "Fu*&ed Up Beyond All Recognition"

I kid you not.

It is a form of encouragement to fellow programmers who have also gone through trial by fire trying to generate working code.

****ed up beyond all recognition it is..

Fully Operational Obesity. It's a subliminal message cause its hard for us guys not to get fat sitting around programming all day. Hell i know I always have coffee, sprite, 3 snacks buy me when im crunching on some code for long hours. Not to mention a box of cereal for back up!
