在thinkphp中实现facade的方法

主要的思想是利用call_user_func_array()和容器结合使用的。

核心代码,理解都在注释中:

<?php

//reqeuestFacade.php

    namespace facade{

        class Request extends Facade{

            public function getFacadeName(){

                return 'request';

            }

        }

    }

 

?>

 

<?php

//facade.php

namespace facade{

    class Facade{

 

        public static function createFacade(){

            $class = static::class; //在这个获取的$class其实是facade\reqeust

            //在这里利用static::得到getFacadeName,返回真正的request的变量名

            $facadeClass = static::getFacadeName();

 

            if ($facadeClass) {

                $class = $facadeClass;

            } elseif (isset(self::$bind[$class])) {

                $class = self::$bind[$class];

            }

            //echo $class;

            利用容器去获取reqeust,而不是facade\reqeust

            return \Container::get($class);

        }

     

        public static function __callStatic($method, $params)

        {

            return call_user_func_array([static::createFacade(), $method], $params);

        }

    }

}

 

 

?>

  

下面测试代码

reqeust.php

<?php

 

class Request{

    public $name = 'Real Request';

 

    public  function sayName(){

        echo $this->name;

    }

 

}

 

?>

  

test.php

<?php

 

    use facade\Request;

 

    include "Container.php";

    include "Facade.php";

    include "RequestFacade.php";

    include "Request.php";

 

    Request::sayName();

 

?>

  

以上就是在thinkphp中实现facade的方法的详细内容
