| 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.
