How to make Yii2 methods available to OpenCart classes?

Question

Yii

Hello!
I need an online store and the functionality on the initial plan is standard, so I decided to take OpenCart, but further expansion may require Yii2, which I just started learning.
Is it possible to make Yii2 functionality available inside OpenCart classes? That is, so that Yii2 can use its own models, etc.?

Answer 1

Add Yii via composer, write somewhere in index.php

require(__DIR__ . '/../vendor/yiisoft/yii2/Yii.php');
$yiiConfig = require(__DIR__ . '/../config/yii/web.php');
new yii\web\Application($yiiConfig);
