本文实例讲述了Yii框架日志记录Logging操作。分享给大家供大家参考，具体如下：
1、Yii::getLogger()->log($message, $level, $category = 'application')
2、Yii::trace($message, $category = 'application');
3、Yii::error($message, $category = 'application');
4、Yii::warning($message, $category = 'application');
5、Yii::info($message, $category = 'application');
在config，main.php配置
默认配置：
'log'=> [ 'traceLevel' => YII_DEBUG ? 3 : 0, 'targets' => [ [ 'class' => 'yii/log/FileTarget', 'levels' => ['error', 'warning'], ], ], ],
修改
'log' => [ 'traceLevel'=> YII_DEBUG ? 3 : 0, 'targets' => [ [ 'class' => 'yii/log/FileTarget', 'levels' => ['error', 'warning','info','trace'], ], [ 'class'=> 'yii/log/FileTarget', 'levels' => ['info'], 'categories' => ['rhythmk'], 'logFile' => '@app/runtime/logs/Mylog/requests.log', 'maxFileSize' => 1024 * 2, 'maxLogFiles' => 20, ], ], ],
输出日志：
Yii::getLogger()->log("开始写自定义日志",Logger::LEVEL_ERROR);Yii::trace("trace,开发调试时候记录");Yii::error("error,错误日志");Yii::warning("warning,警告信息");Yii::info("info,记录操作提示"); Yii::info("info .... ","rhythmk");//输出自定义目录日志,@app/runtime/logs/Mylog/requests.log 希望本文所述对大家基于Yii框架的PHP程序设计有所帮助。
