I think it's useful if we draw some attention to late static binding here:
<?php
class A {
    const MY_CONST = false;
    public function my_const_self() {
        return self::MY_CONST;
    } 
    public function my_const_static() {
        return static::MY_CONST;
    } 
}

class B extends A {
   const MY_CONST = true;
}

$b = new B();
echo $b->my_const_self ? 'yes' : 'no'; // output: no
echo $b->my_const_static ? 'yes' : 'no'; // output: yes
?>
