How to determine in Yii2 that the page is the main one in the view file?
At the same time, you need to define it in view/layout/main.php

Answer 1

If I understand correctly, then you need to find out the name of the controller in main.php, then:

if ((Yii::app()->controller->id == 'site') and (Yii::app()->controller->action->id == 'index'))  {
// тут код
}

Answer 2

Yii::$app->request->url == Yii::$app->homeUrl
