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.
