Slim v4 Creating Log File - php

Question

So, my issue is that I'm having trouble to make Slim record all its actions inside a file (for example : app.log). I ran across a lot of tutorials and other forum similar to this one but the issue was that they were using the v3 of the Slim Framework.
I saw some post suggesting things like this inside a settings.php :
return [
'settings' => [
'displayErrorDetails' => true, // set to false in production
'addContentLengthHeader' => false, // Allow the web server to send the content-length header
// Renderer settings
'renderer' => [
'template_path' => __DIR__ . '/../templates/',
],
// Monolog settings
'logger' => [
'name' => 'my-app',
'path' => __DIR__ . '/../logs/' . $logDate->format('Y-m-d') . 'app.log',
],
],
];
But the issue with that method is that, well, settings aren't set up this way anymore in v4. So here I am. Stuck. If anybody could give me a hand, it'll help a lot !

To load the settings within a container you have to add a container definition for it.
Example settings file: config/settings.php
return [
// set to false in production
'displayErrorDetails' => true,
// Renderer settings
'renderer' => [
'template_path' => __DIR__ . '/../templates/',
],
// Monolog settings
'logger' => [
'name' => 'my-app',
'path' => __DIR__ . '/../logs/' . date('Y-m-d') . '_app.log',
],
];
Example container entry in config/container.php:
use Psr\Container\ContainerInterface;
// ...
return [
// ...
'settings' => function () {
return require __DIR__ . '/settings.php';
},
// Add more entries here ...
}
To fetch the settings within the container use this:
use Psr\Container\ContainerInterface;
use Psr\Log\LoggerInterface;
// ...
return [
// ...
LoggerInterface::class => function (ContainerInterface $container) {
$settings = $container->get('settings');
$name = $settings['logger']['name'];
$logger = new Logger($name);
// Add logger handler...
return $logger;
},
// ...
}
Tip: For autowiring support it's better to use an collection object instead of an simple "string" as container identifier. Read more
