"Declaration of Combodo\iTop\Cas\CASLogger::emergency($message, array $context = []) must be compatible with Psr\Log\LoggerInterface::emergency(Stringable|string $message, array $context = [])" psr/log 3.0.0 brings the BC break Switching to 2.0.0 is nice as it will bring improvements for PHP 8.0+ ! So adding psr/log ^2.0.0 to composer.json
PSR Log
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.
