Minicli provides a Logger class that can be used to log messages to a file.


The Logger class is configured via the config/logging.php file. The following configuration keys are available:



use Minicli\Logging\LogLevel;
use Minicli\Logging\LogType;

return [
     * Logging Configuration
     * --------------------------------------------------------------------------
     * This configuration defines the logging settings for your application.

    'logging' => [
        'type' => LogType::SINGLE->value,

        'level' => LogLevel::INFO->value,

        'timestamp_format' => 'Y-m-d H:i:s',

The type key defines the type of logging to be used. The following types are available:

  • LogType::SINGLE - A single file will be used to log all messages.
  • LogType::DAILY - A new file will be created for each day.

The level key defines the minimum level of logging to be used. The following levels are available:

  • LogLevel::DEBUG - Detailed debug information.
  • LogLevel::INFO - Interesting events. Examples: User logs in, SQL logs.
  • LogLevel::WARNING - Exceptional occurrences that are not errors. Examples: Use of deprecated APIs, poor use of an API, undesirable things that are not necessarily wrong.
  • LogLevel::ERROR - Runtime errors that do not require immediate action but should typically be logged and monitored.

The timestamp_format key defines the format of the timestamp to be used in the log messages. The default value is Y-m-d H:i:s.


The Logger class is a built-in service (by implementing ServiceInterface) resgistered as a service when the Appclass is instanciated, allowing it to be used by the App and each command controller:

// From the App instance
$app->logger->log('This is a log message');

// From a command controller
$this->logger->log('This is a log message');

The log method accepts two parameters:

  • $message - The message to be logged.
  • $level - The level of the message to be logged. The default value is the one defined in the config file.

Besides the log method, the following methods are available:

  • debug - Logs a message with the DEBUG level.
  • info - Logs a message with the INFO level.
  • warning - Logs a message with the WARNING level.
  • error - Logs a message with the ERROR level.
