This repository holds all interfaces/classes/traits related to PSR-3.
Note that this is not a logger of its own. It is merely an interface that describes a logger. See the specification for more details.
composer require psr/log
If you need a logger, you can use the interface like this:
<?php use Psr\Log\LoggerInterface; class Foo { private $logger; public function __construct(LoggerInterface $logger = null) { $this->logger = $logger; } public function doSomething() { if ($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 and
implement Psr\Log\LoggerInterface in your code. Please read the
specification text
for details.
