	PSR Log
	=======

	This repository holds all interfaces/classes/traits related to
	[PSR-3](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-3-logger-interface.md).

	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
	------------

	```bash
	composer require psr/log
	```

	Usage
	-----

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

	```php
	<?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](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-3-logger-interface.md)
	for details.
