Database Preparing

Package provides two way for preparing database:

  1. Raw SQL. You can use it with the migration package used in your application.

  2. DbSchemaManager for ensureTable(), ensureNoTable() methods for log table (by default {{%yii_log}}).

// Create db schema manager
$dbSchemaManager = new DbSchemaManager($db);

// Ensure table with default name

// Ensure table with custom name

// Ensure no table with default name

// Ensure no table with custom name

General usage

When creating an instance of \Yiisoft\Log\Logger, you must pass an instance of the database connection.

Creating a target:

$dbTarget = new \Yiisoft\Log\Target\Db\DbTarget($db, $table);
  • $db (\Yiisoft\Db\Connection\ConnectionInterface) - The database connection instance.
  • $table (string) - The name of the database table to store the log messages. Defaults to "log".

Creating a logger:

$logger = new \Yiisoft\Log\Logger([$dbTarget]);

You can use multiple databases to store log messages:

 * @var \Yiisoft\Db\Connection\ConnectionInterface $mysqlDb
 * @var \Yiisoft\Db\Connection\ConnectionInterface $sqliteDb

$logger = new \Yiisoft\Log\Logger([
    new \Yiisoft\Log\Target\Db\DbTarget($mysqlDb),
    new \Yiisoft\Log\Target\Db\DbTarget($sqliteDb),


For a description of using the logger, see the yiisoft/log package.
