推荐答案

只要你的$ myclass有一个成员/属性是一个实例本身，它就会像这样工作。

As long as your $myclass has a member/property that is an instance itself it will work just like that.

class foo {
   public $bar;
}

class bar {
    public function hello() {
       return "hello world";
    }
}

$myclass = new foo();
$myclass->bar = new bar();
print $myclass->bar->hello();
