Monolog for Yii 2
The Monolog integration for the Yii framework.
Requirements
- PHP 5.4 or above
- Yii 2.0.0 or above
Instalation with composer
- Open your project directory;
- Run
composer require mero/yii2-monolog
to add Monolog in your project vendor.
Configuration
To configure Monolog component in Yii2, use the structure exemplified below. The channel "main" is required in component and used when no channel is setted to use a logger.
return [
//....
'components' => [
'monolog' => [
'class' => '\Mero\Monolog\MonologComponent',
'channels' => [
'main' => [
'handler' => [
//Handler object or array configuration
],
'processor' => [],
],
],
],
],
//....
];
You can configure multiple channels and different handlers and processors for each channel.
Example
return [
//...
'channels' => [
'main' => [
'handler' => [
[
'type' => 'stream',
'path' => '@app/runtime/logs/main_' . date('Y-m-d') . '.log',
'level' => 'debug'
]
],
'processor' => [],
],
'channel1' => [
'handler' => [
[
'type' => 'stream',
'path' => '@app/runtime/logs/channel1_' . date('Y-m-d') . '.log',
'level' => 'debug'
]
],
'processor' => [],
],
'channel2' => [
'handler' => [
[
'type' => 'stream',
'path' => '@app/runtime/logs/channel1_' . date('Y-m-d') . '.log',
'level' => 'debug'
]
],
'processor' => [],
],
],
//...
];
Handlers
You can add handlers in their channels using the array structure or object structure.
Array structure
Using the array structure, you have a better readability of the configuration of their handlers.
Example
return [
//...
'handler' => [
[
'type' => 'stream',
'path' => '@app/runtime/logs/log_' . date('Y-m-d') . '.log',
'level' => 'debug'
]
],
//...
];
Warning: this option does not have any existing handlers in monolog. See the handlers page more details.
Object structure
Using the object structure, you will be informing instantiated objects already declared their respective handlers.
Example
return [
//...
'handler' => [
new \Monolog\Handler\StreamHandler(
__DIR__.'/../runtime/logs/system.log',
\Monolog\Logger::DEBUG
)
],
//...
];
Using Yii2 Monolog
To use Yii 2 Monolog simply call the method getLogger
component informing which channel is used.
Example
namespace app\controllers;
use Yii;
use \yii\web\Controller;
class ExampleController extends Controller
{
/**
* This action register "Hello world" in channel
* "main"(default when no value is setted on "getLogger" method).
*/
public function actionFirstExample()
{
$monologComponent = Yii::$app->monolog;
$logger = $monologComponent->getLogger();
$logger->log('info', 'Hello world');
}
/**
* This action register "Hello world" in channel "channel1".
*/
public function actionSecondExample()
{
$monologComponent = Yii::$app->monolog;
$logger = $monologComponent->getLogger("channel1");
$logger->log('info', 'Hello world');
}
}
