yii2 Components Creating and using application components
Example
Steps to Create component:
- Create a folder named
componentsin your project root folder - Create your component inside components folder e.g.:
MyComponent.php
namespace app\components;
use Yii;
use yii\base\Component;
use yii\base\InvalidConfigException;
class MyComponent extends Component
{
public function demo()
{
return "welcome";
}
}
- Register your component inside the
config/web.phpfile
components' => [
'mycomponent' => [
'class' => 'app\components\MyComponent',
],
]
Now you can use your component method:
namespace app\controllers;
use Yii;
class DemoController extends \yii\web\Controller
{
public function actionTest()
{
echo Yii::$app->mycomponent->demo();
}
}
