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.


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


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');

        // 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.

Something went wrong with that request. Please try again.
