get_class (): 获取当前调用方法的类名；
get_called_class():获取静态绑定后的类名；
有例为证：
class Foo{ ?????public function test(){ ????????var_dump(get_class()); ?????} ?????public function test2(){ ???????var_dump(get_called_class()); ?????} ?????public static function test3(){ ???????var_dump(get_class()); ?????} ?????public static function test4(){ ???????var_dump(get_called_class()); ?????} ??} ??class B extends Foo{ ??} ??$B=new B(); ??$B->test(); ??$B->test2(); ??Foo::test3(); ??Foo::test4(); ??B::test3(); ??B::test4();输出结果：
string ‘Foo‘ (length=3)string ‘B‘ (length=1)string ‘Foo‘ (length=3)string ‘Foo‘ (length=3)string ‘Foo‘ (length=3)string ‘B‘ (length=1)
