Yii::getLogger()->log($message, $level, $category = ‘application‘) Yii::trace($message, $category = ‘application‘); Yii::error($message, $category = ‘application‘); Yii::warning($message, $category = ‘application‘); Yii::info($message, $category = ‘application‘);
配置：
/config/web.php
components->log
默认配置：
‘log‘ => [
‘traceLevel‘ => YII_DEBUG ? 3 : 0,
‘targets‘ => [
[
‘class‘ => ‘yii\log\FileTarget‘,
‘levels‘ => [‘error‘, ‘warning‘],
],
],
],
现修改配置如下：
‘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,
],
],
],
使用日志（将日志记录到log）
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");
输出自定义目录日志
// 日志文件在输出目录 @app/runtime/logs/Mylog/requests.log
Yii::info("info .... ","rhythmk");
