8 describes a logger. See the specification for more details.

10 Usage
11 -----
12  
13 If you need a logger, you can use the interface like this:
14  
15 ```php
16 <?php
17  
18 use Psr\Log\LoggerInterface;
19  
20 class Foo
21 {
22 private $logger;
23  
24 public function __construct(LoggerInterface $logger = null)
25 {
26 $this->logger = $logger;
27 }
28  
29 public function doSomething()
30 {
31 if ($this->logger) {
32 $this->logger->info('Doing work');
33 }
34  
35 // do something useful
36 }
37 }
38 ```
39  
40 You can then pick one of the implementations of the interface to get a logger.
41  
42 If you want to implement the interface, you can require this package and
43 implement `Psr\Log\LoggerInterface` in your code. Please read the
44 [specification text](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-3-logger-interface.md)
45 for details.
