Configuring the writer(s)

Loggers must have at least one writer.

A writer is an object that inherits from Dot\Log\Writer\AbstractWriter. A writer's responsibility is to record log data to a storage backend.

Writing to a file (stream)

You can separate logs into multiple files using writers and filters. For example warnings.log, errors.log, all_messages.log.

The following is the simplest example to write all log messages to /log/dk.log

return [
    'dot_log' => [
        'loggers' => [
            'my_logger' => [
                'writers' => [
                     'FileWriter' => [
                        'name' => 'FileWriter',
                        'priority' => \Dot\Log\Manager\Logger::ALERT, // this is equal to 1
                        'options' => [
                            'stream' => __DIR__ . '/../../log/dk.log',
                        ],
                    ],
                ],
            ]
        ],
    ],
];

• The FileWriter key is optional, otherwise the writers array would be enumerative instead of associative.
• The name key is a developer-provided name for that writer, the writer name key is mandatory.

The priority key does not affect the errors that are written. It is a way to organize writers.

The priority key is optional.

The key stream is required only if writing into streams/files.
