There is example of using Monolog with PHP-DI (from manual, there are 2 files - index.php and config.php:
<?php
// config.php
use Monolog\Logger;
use Monolog\Handler\StreamHandler;
return [
// ...
Psr\Log\LoggerInterface::class => DI\factory(function () {
$logger = new Logger('mylog');
$fileHandler = new StreamHandler('path/to/your.log', Logger::DEBUG);
$fileHandler->setFormatter(new LineFormatter());
$logger->pushHandler($fileHandler);
return $logger;
}),
];
This config.php is using in the below code:
// index.php
use DI\ContainerBuilder;
require __DIR__ . '/../vendor/autoload.php';
$containerBuilder = new ContainerBuilder;
$containerBuilder->addDefinitions(__DIR__ . '/config.php');
$container = $containerBuilder->build();
How could I use it now in index.php? Regularly I use Monolog this way:
$log = new Logger('name');
$log->warning('Foo');
But how to call it with Container?
I was able to do it in simple $container->set(), $container->get() mode. But in this way using Container Builder I can't find a way to do it. Moreover when I make var_dump($container)
there are no any logger's signs in it.
You need to replace $log = new Logger('name')
with:
$log = $container->get(\Psr\Log\LoggerInterface::class);
