This article example describes the Yii framework logging Logging operations. Share it for your reference, as follows:

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');

Configuration in config, main. php

components->log

Default configuration:

'log'=> [
      'traceLevel' => YII_DEBUG ? 3 : 0,
      'targets' => [
        [
          'class' => 'yii\log\FileTarget',
          'levels' => ['error', 'warning'],
        ],
      ],
    ],

Modify

'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,
        ],
      ],
    ],

Yii::getLogger()->log(" Start writing custom logs ",Logger::LEVEL_ERROR);
Yii::trace("trace, Record when developing and debugging ");
Yii::error("error, Error log ");
Yii::warning("warning, Warning message ");
Yii::info("info, Record operation tips ");

Yii::info("info .... ","rhythmk");
