Kohana 3 命令行输出缓冲？

发布于 2024-10-14 16:04:47 字数 265 浏览 6 评论 0原文

我正在使用 Kohana 3，并且有一个扩展 Kohana_Controller 的控制器。我使用以下命令从命令行调用它：

php /path/to//index.php --uri="url/path"

它工作得很好，但是这个特定的脚本需要很长时间，并且在执行期间我正在回显状态消息（回显“状态消息”；），但直到脚本执行完毕后才会出现任何消息执行完成。

我想查看回显的状态消息，有人可以告诉我该怎么做吗？

谢谢

I am using Kohana 3 and I have a controller that extends Kohana_Controller. I call it from the command line using:

php /path/to//index.php --uri="url/path"

It works just fine, but this particular script takes a long time and during the execution I am echoing status messages (echo 'status message';) but none of the messages appear until after the script has completed executing.

I want to see the status messages as they are echoed, can anyone tell me how to do it?

Thanks

看起来 Kohana::init() （可能在您的 bootsrap 中调用）调用了 ob_start()。这意味着该点之后的所有输出都包含在输出缓冲区中。要阻止这种情况，请在控制器的 before 方法中添加 ob_end_flush() 来输出可能已输出的任何内容并关闭输出缓冲。之后您发出的任何回声都应该立即输出。

所以你的代码看起来像：

  Controller_CLI extends Controller {
       public function before() {
              // empty the output buffre
              ob_end_flush();

              // call parent before() just incase there's anything 
              // in the parent before that you need/want to execute
              parent::before();
       }
  }

It looks like Kohana::init() (likely called in your bootsrap) calls an ob_start(). This means that everything output after that point is contained in the output buffer. To stop this, in your before method in your Controller add ob_end_flush() to output anything that may have already been output and turn off output buffering. Any echo's you make after that should be output immediately.

So your code with look like:

  Controller_CLI extends Controller {
       public function before() {
              // empty the output buffre
              ob_end_flush();

              // call parent before() just incase there's anything 
              // in the parent before that you need/want to execute
              parent::before();
       }
  }
