Simple example of static late binding in PHP

I haven’t used this new feature much. It’s not really new at all. Give it a try. Inheriting static classes is very convenient now

class A {

protected static $def = '123456';

public static function test() {

echo get_class(new static);

　}

　public static function test2() {

echo static::$def;

　}

　}

class B extends A {

protected static $def = '456789';

　}

class C extends A {

protected static $def = 'abcdef';

　}

echo B::test();

echo '

　;

echo C::test();

echo '

　;

echo B::test2();

echo '

　;

echo C::test2();

echo '

　;

echo A::test();

echo '

　;

echo A::test2();

echo '

　;

// Output results

　B

C

　456789

abcdef

　A

　123456
