CakePHP log(日志)操作（摘录）

CakePHP 的日志文件放置在目录 app/tmp/logs/ 下，下面是几个例子

//Executing this inside a CakePHP class:
$this->log("Something didn't work!");

//结果追加到  app/tmp/logs/error.log
2007-11-02 10:22:02 Error: Something didn't work!

//Executing this inside a CakePHP class:
$this->log('A debugging message.', LOG_DEBUG);

//结果追加到 app/tmp/logs/debug.log (rather than error.log)
2007-11-02 10:22:02 Error: A debugging message.

//Executing this inside a CakePHP class:  
$this->log('A special message for activity logging', 'activity'); 

//结果追加到 app/tmp/logs/activity.log (rather than error.log)
2007-11-02 10:22:02 Activity: A special message for activity logging
