Parent :: method () - call a non-stationary method

Question

I do not understand the concept of calling a parent method in PHP. The parent method is not static, but it is called statically - usually PHP generates an error / warning.

The question is, is this a quirk from PHP, or is it how it should be in OOP?

Taking an example from php.net:

<?php
class A {
    function example() {
        echo "I am A::example() and provide basic functionality.<br />\n";
    }
}

class B extends A {
    function example() {
        echo "I am B::example() and provide additional functionality.<br />\n";
        parent::example();
    }
}

$b = new B;

// This will call B::example(), which will in turn call A::example().
$b->example();
?>

In PHP 5, calling non-static methods statically generates E_STRICT level warnings.
