Calling closure assigned to object property directly

如果是这样的话:

class test{
  function one(){
     $this->two()->func(); //Since $test is returned, why can I not call func()?
  }

  function two(){
    $test = (object) array();
    $test->func = function(){
       echo  Does this work? ;
    };
    return $test;
  }
}

$new = new test;
$new->one(); //Expecting  Does this work?

因此,我的问题是,当我从职能一中讲职能二时,职能二是把印数作为回报,该变量具有随附的结局。为什么我不能把这称作一种链条的方法?

Edit I just remembered that this can also be done by using $this->func->__invoke() for anyone that needs that.

Answer 1

由于目前这是对购买力平价的一种限制。你正在做的是合乎逻辑的,应当有可能。事实上,你可以通过书面方式围绕限制开展工作:

function one(){
    call_user_func($this->two()->func);
}

或

function one(){
    $f = $this->two()->func;
    $f();
}

我知道Stupid。
