In PHP5.3, the keyword static is added to the class to implement latestaticbinding. let's take a look at an example to learn how to use this new feature, actually, it's not new. try it. it's very convenient to inherit static classes now.

<? Phpclass A {protected static $ def = '000000'; public static function test () {echo get_class (new static);} public static function test2 () {echo static :: $ def ;}} class B extends A {protected static $ def = '000000';} 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'
';
