php内部类支持

Question

PHP版本5.3或之后是否支持内部类？例:

class MyClass{
    class PrivateClass1{

    }
    class PrivateClass2{

    }
    class PrivateClass3{

    }

    private $obj1;
    private $obj2;
    private $obj3;

    __construct(){
        $obj1 = new PrivateClass1();
        $obj2 = new PrivateClass2();
        $obj3 = new PrivateClass3();
    }
}

Answer 1

PHP目前(5.4.3)不支持内部/朋友类

并且wiki中也没有RFC要求添加这样的功能.
