Yii框架使用魔术方法实现跨文件调用功能示例

<?php
class aApi
{
  public static function tt1($name, $age)
  {
    print_r($name);
    echo $age;
  }
}
class aAdapter
{
  public function __call($func, $params)
  {
    $class = substr(get_called_class(), 0, -7) . 'Api';
    return call_user_func_array(array($class, $func), $params);
  }
}
class aFacade
{
  public static function __callstatic($func, $params)
  {
    // 这里也可以用debug_backtrace()
    $class = substr(get_called_class(), 0, -6) . 'Adapter';
    $obj = new $class();
    return call_user_func_array(array($obj, $func), $params);
  }
}
class aController
{
  public function actionC()
  {
    aFacade::tt1(['name'], 'age');
  }
}
$a = new aController;
$a->actionC();
