thinkphp中facade的实现

主要的思想是利用call_user_func_array()和容器结合使用的。
容器用的上一篇写的容器连接如下
链接描述
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();

?>
最后的结果
