Overriding functions

PHP allows us to redefine functions in sub-classes, which means we can make the poodle class have its own version of bark(). This is done by simply redefining the function the function inside the child class, making the poodle class look like this:

class poodle extends dog {
    public function bark() {
        print "Yip!\n";

We'll come back to inheritance and all the neat ways you can use it after we take a look at objects - actual instances of our classes.
