Most of the Yii beginner write parameter in main.php because that’s pattern comes in installed Yii framework. This is fine if you have less parameter but if you are building large web portal or application then it’s very hard to manage everything in mail.php because of its main config file. So the best way is creating separate params.php in the same directory and includes it in your main.php file. The check is the example of params.php and main.php files for create custom params in yii framework.

config/main.php :

'params'=>require(dirname(__FILE__).'/params.php'),

config/params.php :

<?php
return array(
 'defaultPageSize'=>10,
 'websiteName'=>'ezeelive.com',
 'copyrightInfo'=>'Copyright &copy; '.date("Y").' Ezeelive Technologies. All Rights Reserved.',
 ...
 ...
);
?>

In Yii2 Framework:

1. config/main.php (advance backend application):

<?php // You can add your custom params file here $params = array_merge( require(__DIR__ . '/../../common/config/params.php'), require(__DIR__ . '/../../common/config/params-local.php'), require(__DIR__ . '/params.php'), require(__DIR__ . '/params-local.php') ); return [ 'id' => 'backend-app',
        'name' => 'Backend App',
        'basePath' => dirname(__DIR__),
        'bootstrap' => ['log'],
        'controllerNamespace' => 'backend\controllers',
        'modules' => [],
        'components' => [
            'log' => [
                'traceLevel' => YII_DEBUG ? 3 : 0,
                'targets' => [
                    [
                        'class' => 'yii\log\FileTarget',
                        'levels' => ['error', 'warning'],
                    ],
                ],
            ],
            'errorHandler' => [
                'errorAction' => 'site/error',
            ],
        ],
        'params' => $params,
    ];

In this example, we are using params.php file.

2. In params.php:

<?php return [ 'adminEmail' => 'info@ezeelive.com',
 ];

3. Access param variable:

  $params['mandrill_api_key'] 
  OR 
  \Yii::$app->params['mandrill_api_key']
