PHP中类的嵌套及继承
在A类中嵌套个B类,且B类是继承的C类,可以实现吗?

------解决方案--------------------
类是肯定不能嵌套的啦.
------解决方案--------------------
他说嵌套应该是说实例化进来一个类吧。。。。。。。。=_=
------解决方案--------------------
嵌套是什么意思?实例化的话当然可以,类中定义类应该不可以吧。
------解决方案--------------------
没这样的写法.你为什么要这么写? 


你是不是要实现这样?


PHP code
class C{    public $C = 'Cname';}class B extends  C{    public $B = 'Bname';}class A{        public $B;    function load()    {        $this -> B  = new B();    }}$A = new A();$A -> load();echo $A -> B -> C;echo $A -> B -> B;<div class="clear">
                 
              
              
        
            </div>
