yii2自定义日志

1.新增公共配置文件（common/config/main-local.php）

'log' => [
    'traceLevel' => YII_DEBUG ? 3 : 0,
    'targets' => [
        [
            'class' => 'yii\log\FileTarget',
            'logFile' => '@runtime/logs/info.log',
            'levels' => ['info'],
            //'categories' => ['application'],
        ],
    ],
],

2.公共数据模型文件中使用

public static function findByMatchList($product_id, $district_id)
{
    $query = Clerk::find()
        ->joinWith(['clerkItems items'], true, 'INNER JOIN')
        ->where(['LIKE', 'items.product_ids', ','.$product_id.',']);

    if($district_id > 0)
    {
        $query->joinWith(['clerkArea area'], true, 'INNER JOIN')
            ->andWhere(['area.district_id' => $district_id]);
    }

    $list = $query->all();
    Yii::getLogger()->log('findByMatchList, $product_id:'.$product_id.'$product_id:'
        .$district_id.', data:'.serialize($list).'sql:'.$query->createCommand()->rawSql, Logger::LEVEL_INFO);
    return $list;
}
