A simple example of log output to file and database in yii2

Edit config/web.php

First the log must be enabled

    'bootstrap' => [
        'log'
    ],

[file]

##

    'components' => [
        'log' => [
            'targets' => [
                [
                    'class' => 'yii\log\FileTarget',
                    'exportInterval' => 1,
                ],
            ],
        ],

The default output is to runtime/logs/app.log

Note that the webserver or console user must have permission to write to the file

[database]

        'log' => [
            'targets' => [
                [
                    'class' => 'yii\log\DbTarget',
                    'levels' => ['error', 'warning', 'trace'],
                ]
            ]
        ],

The default output is the {{%log}} table under the database corresponding to the db component

Run the following command in the yii2 root directory to generate the corresponding table schema

./yii migrate --migrationPath=@yii/log/migrations/

Note that config/console.php must also have the same configuration as web.php, otherwise the command execution will not be successful.

You can also configure different log modes according to different environments

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