有关PHP回调函数的乌云。

本人较菜，请问各位侠士，如何在PHP中达到EventStack的NotifyWatcher方法可以将取得的数据返还给welcome.php指定的回调函数，我哪里写的不对啊 ？？？

出现的错误为：Fatal error: Function name must be a string in /home/latel/Workspace/new_zhebo/module/EventStack.php on line ××

你给全错误信息不经行了吗？
Fatal error: Function name must be a string in C:\wamp\www\newzhebo\module\ EventStack.php on line 157
不就是 EventStack.php 的 157 行出错吗？
EventStack.php 

  1. 143    private function toast($iKey) {144        //推送事件至相应的观察者145        if (array_key_exists($this->_aEventStack[$iKey]["stamp"], $this->_aWatcherRegistry)) {146            $mCallback = $this->_aWatcherRegistry[$this->_aEventStack[$iKey]["stamp"]](147                $this->_aEventStack[$iKey]["stamp"],148                $this->_aEventStack[$iKey]["value"]149            );150            //如果指定了回调函数，依据观察者返回的数据，做出具体的操作151            if (isset($this->_aEventStack[$iKey]["fHandler"]) && !$mCallback) {152                echo $func = $this->_aEventStack[$iKey]["fHandler"];153                echo 1;154                $func($mCallback);155            } else {156                echo 2;157                $func(null); //这个 $func 在哪里赋值的？            }        }    }

154 的是在 152 赋值的，哪 157 的 $func 在哪里赋值的？

至少要把 $func = $this->_aEventStack[$iKey]["fHandler"]; 放到条件分支外面吧？

我把代码改成这样，还是上面的错误。 

  1. private function toast($iKey) {
  2. //推送事件至相应的观察者
  3. if (array_key_exists($this->_aEventStack[$iKey]["stamp"], $this->_aWatcherRegistry)) {
  4. $mCallback = $this->_aWatcherRegistry[$this->_aEventStack[$iKey]["stamp"]](
  5. $this->_aEventStack[$iKey]["stamp"],
  6. $this->_aEventStack[$iKey]["value"]
  7. );
  8. //如果指定了回调函数，依据观察者返回的数据，做出具体的操作
  9. $func = $this->_aEventStack[$iKey]["fHandler"];
  10. if (isset($this->_aEventStack[$iKey]["fHandler"]) && !$mCallback) {
  11. echo 1;
  12. $func($mCallback);
  13. } else {
  14. echo 2;
  15. $func(null);
  16. }
  17. }
  18. }
