How to create an independent script run on Magento 2? [duplicate]

Question

I'd like to create a file in the root folder (e.g. test.php) that I'll be able to do functions programmatically like update product attributes or something like that.

Can you show me some sample?

Thanks

You can use something like that like a sample:

<?php

use Magento\Framework\App\Bootstrap;

require __DIR__ . '/app/bootstrap.php';

$params = $_SERVER; 
$bootstrap = Bootstrap::create(BP, $params);

$obj = $bootstrap->getObjectManager();

$state = $obj->get('Magento\Framework\App\State');
$state->setAreaCode('frontend');

$productCollection = $obj->create('Magento\Catalog\Model\ResourceModel\Product\CollectionFactory');
$collection = $productCollection->create()
            ->addAttributeToSelect('*')
            ->load();

foreach ($collection as $product){

     echo 'SKU:  '.$product->getSku().'<br>';   
     echo 'Name:  '.$product->getName().'<br>';
     echo 'Price:    '.$product->getPrice().'<br>';
     echo 'Special price:    '.$product->getSpecialPrice().'<br>';
     echo '----------------------------<br>';       

}
