PHPDoc和后期(静态或动态)绑定 [英] PHPDoc and late (static or dynamic) binding

问题描述

大多数PHP IDE都依赖phpdoc来获取有关表达式类型的提示.但是，我经常使用这种模式，但似乎没有涉及到它:

Most PHP IDEs rely on phpdoc to get hints about the type of an expression. Yet, I use frequently this pattern, which doesn't seem to be covered:

class Control {
    private $label = '';

    /** @return ??? */
    public static function Make(){ return new static(); }

    /** @return ??? */
    public function WithLabel($value){  $this->label = $value;  return $this;  }

    /** @return void */
    public function Render(){ /* ... */ }
}

class Textbox extends Control {
   private $text = '';

    /** @return ??? */
    public function WithText($text){  $this->width = $text;  return $this;  }
}

现在我可以使用这样的类:

Now I can use the classes like this:

Textbox::Make()           // <-- late static binding, returns Textbox
   ->WithLabel('foo')     // <-- late dynamic binding, returns Textbox
   ->WithText('bar')      // <-- normal binding, returns Textbox
   ->Render();

是否可以用某种方式替换'???'，以使输入信息正确无误?

Is there any way to replace the '???'s with something so that the typing information is correct?

推荐答案

/** @return Control */

非静态:

/** @return $this */

但是phpdoc手册中没有记录

but it's not documented in phpdoc manual
