README

This repository holds all interfaces/classes/traits related toPSR-3.

Note that this is not a logger of its own. It is merely an interface thatdescribes a logger. See the specification for more details.

Installation

composer require psr/log

Usage

If you need a logger, you can use the interface like this:

<?phpusePsr\Log\LoggerInterface;class Foo{private$logger;publicfunction__construct(LoggerInterface$logger =null)    {$this->logger =$logger;    }publicfunctiondoSomething()    {if ($this->logger) {$this->logger->info('Doing work');        }try {$this->doSomethingElse();        }catch (Exception$exception) {$this->logger->error('Oh no!',array('exception' =>$exception));        }// do something useful    }}

You can then pick one of the implementations of the interface to get a logger.

If you want to implement the interface, you can require this package andimplementPsr\Log\LoggerInterface in your code. Please read thespecification textfor details.
