I am trying to reuse ExportToCSVFromList that works in Yii1.1 with something similar for Yii2.

Is there any same as ExportToCSVFromList method, that works for Yi1.1 for Yii2 as well?

My Answer:
In Yii2, you can achieve similar functionality by using the `yii2-export` extension. This extension provides various export formats including CSV. Here is an example of how you can export data to a CSV file in Yii2:

1. First, you need to install the `yii2-export` extension. You can do this by adding the following line to your `composer.json` file:

json
"kartik-v/yii2-export": "@dev"


2. Run `composer update` to install the extension.

3. Next, you can use the `ExportMenu` widget provided by the extension to export data to a CSV file. Here is an example of how you can use it in your view file:

php
use kartik\export\ExportMenu;

$dataProvider = new \yii\data\ArrayDataProvider([
'allModels' => $data,
]);

echo ExportMenu::widget([
'dataProvider' => $dataProvider,
'columns' => [
'column1',
'column2',
// add more columns as needed
],
'target' => ExportMenu::TARGET_SELF,
'showConfirmAlert' => false,
'exportConfig' => [
ExportMenu::FORMAT_CSV => false,
],
]);


4. Replace `$data` with the data you want to export to the CSV file.

5. When you render the view file, you will see a button that allows you to export the data to a CSV file.

This is just a basic example of how you can export data to a CSV file in Yii2 using the `yii2-export` extension. You can customize the export functionality further by exploring the documentation of the extension.
