Original GitHub issue: https://github.com/Seldaek/monolog/issues/265

I have manually required "monolog/src/Monolog/Logger.php" in my application (not using Composer) and get a "PHP Fatal error: Interface 'Psr\Log\LoggerInterface' not found in /path/to/monolog/src/Monolog/Logger.php on line 28" when running the application.

I figured I need to download this library (https://github.com/php-fig/log) and so also required "log/Psr/Log/LoggerInterface.php" but was getting the same problem.

How can I use monolog without Composer, instead just by requiring the right files?

@rightaway If you don't want to manually require all files (and you shouldn't) and you don't want to use composer to manage your autoloading, you should implement your own autoloader.

See the PHP docs for spl_autoload_register and the example autoloader implementation in PSR-0.
