use Monolog\Logger; use Monolog\Handler\StreamHandler; $log = new Logger('my_logger'); $log->pushHandler(new StreamHandler('path/to/your.log', Logger::NOTICE)); $log->notice('This is a notice log message.');In this example, we create a new Logger instance named "my_logger" and push a StreamHandler that writes log messages to a file located at "path/to/your.log". We set the log level to Logger::NOTICE, which means that the logger will only output messages that are at the notice level or higher. Then, we use the notice() method to output a simple informational message to the log. This message can be used to track application activities or errors, and can be easily analyzed and debugged using Monolog's powerful logging functionality. Overall, Monolog is a powerful and flexible logging package library for PHP that provides a wide range of logging functionality to help developers analyze and debug complex applications.
