Magento 2: Run code in external file/script

This article shows how to run Magento 2 code in an external file/script. The external file can be inside the Magento root folder or outside of it.

This example considers that the file is present in the Magento 2 root folder. Let us name the file as abc.php. So, we want to execute some code when we open http://example.com/abc.php.

Here is the code to be written in the external file.

<?php
use Magento\Framework\App\Bootstrap;

/**
 * If your external file is in root folder
 */
require __DIR__ . '/app/bootstrap.php';

/**
 * If your external file is NOT in root folder
 * Let's suppose, your file is inside a folder named 'xyz'
 *
 * And, let's suppose, your root directory path is
 * /var/www/html/magento2
 */
// $rootDirectoryPath = '/var/www/html/magento2';
// require $rootDirectoryPath . '/app/bootstrap.php';

$params = $_SERVER;

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

$obj = $bootstrap->getObjectManager();

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

$quoteId = 1;
$quote = $obj->get('Magento\Checkout\Model\Session')
             ->getQuote()
             ->load($quoteId);

echo '<pre>';
print_r($quote->getOrigData());
echo '</pre>';

$productId = 1;
$product = $obj->get('Magento\Catalog\Model\ProductRepository')
               ->getById($productId);

echo '<pre>';
print_r($product->getData());
echo '</pre>';
?>

A good discussion is going on here regarding this topic.

Hope this helps. Thanks.
