 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 '

 ;

 B

C

 456789

abcdef

 A

 123456
