README

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.

Installation

composer require psr/log

Usage

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.
