Wa72SimpleLogger is a collection of very simple logger classes for PHP 5.3 implementing \Psr\Log\LoggerInterface (PSR-3), the common logger interface standardized by the PHP Framework Interop Group (www.php-fig.org).

Wa72SimpleLogger is intended for small projects or testing purposes if you don't need a full-featured logging solution like Monolog.

If you just need to output a few log messages in a small PHP project but want to stick to the PSR-3 standard this package is for you. When your project grows you can simply replace it by a more advanced logging solution like Monolog.


  • \Wa72\SimpleLogger\Filelogger: Log to a file

  • \Wa72\SimpleLogger\ArrayLogger: Keep log messages in an array for later use (e.g. display it to the user)

  • \Wa72\SimpleLogger\ConsoleLogger: Log to the Symfony2 console


  • using composer: add "wa72/simplelogger": "dev-master" to the "require" section of your composer.json

  • Without composer: just include the logger you need: FileLogger.php, ArrayLogger.php or ConsoleLogger.php. Make sure \Psr\Log\LoggerInterface is included as well.


$logger = new \Wa72\SimpleLogger\FileLogger('/path/to/logfile');
$logger->info('This is the first log message');

In one of my projects there was a "fetcher" class that fetched some information from a web service. It needed to log whether this fetch was successfull or not and how many data it fetched. It could be invoked either from the command line, by a background task, or by a user in the admin web page of the application. This was the use case for all 3 logger classes:

  • the fetcher class itself just logs to any PSR-3 compliant logger

  • if called from a background task (cronjob), it is given a FileLogger

  • if called from the command line, it is given a ConsoleLogger

  • if called from the web interface, it is given an ArrayLogger. The output of this logger is then displayed to the user on the web page.
