What are some alternative methods or libraries in PHP that can be used to retrieve and display Amazon product prices without violating Amazon's policies or risking server blacklisting?

When retrieving and displaying Amazon product prices in PHP, it is important to avoid directly scraping Amazon's website as it violates their policies and may lead to server blacklisting. Instead, you can use Amazon's Product Advertising API to access product information in a compliant way. By using the API, you can retrieve product prices and display them on your website without risking any penalties. 

<?php

require 'vendor/autoload.php'; // Include the AWS SDK for PHP

use Aws\ProductAdvertisingAPI\ProductAdvertisingAPIv1Client;
use Aws\Credentials\Credentials;

$credentials = new Credentials('YOUR_ACCESS_KEY', 'YOUR_SECRET_KEY');

$client = new ProductAdvertisingAPIv1Client([
    'credentials' => $credentials,
    'region' => 'YOUR_REGION',
    'version' => 'latest',
]);

$response = $client->getItems([
    'ItemIds' => ['PRODUCT_ID'],
    'PartnerTag' => 'YOUR_TAG',
    'PartnerType' => 'Associates',
    'Marketplace' => 'www.amazon.com',
]);

$item = $response['ItemsResult']['Items'][0];
$price = $item['Offers']['Listings'][0]['Price']['Amount'];

echo 'Price: $' . $price / 100;

?>
