Can I set proxy servers with Goutte for web scraping?

Goutte is a screen scraping and web crawling library for PHP, not Python or JavaScript. While Goutte itself does not have a built-in method to set proxy servers, it relies on GuzzleHttp as its HTTP client, which does support setting proxies.

Here's how you can use a proxy server with Goutte by configuring GuzzleHttp:

require 'vendor/autoload.php';

use Goutte\Client;

$client = new Client();

// Set the proxy configuration
$guzzleClient = new \GuzzleHttp\Client([
    'proxy' => [
        'http'  => 'tcp://proxy.server:port', // Use your proxy URL and port for http
        'https' => 'tcp://proxy.server:port', // Use your proxy URL and port for https
        // If you need authentication:
        // 'http' => 'tcp://username:password@proxy.server:port',
    ],
]);

// Tell Goutte to use your Guzzle client with proxy settings
$client->setClient($guzzleClient);

// Now make a request using Goutte as you normally would
$crawler = $client->request('GET', 'http://example.com');

// Do your scraping as desired
echo $crawler->filter('title')->text();

In this example, replace 'proxy.server:port' with the actual host and port of your proxy server. If your proxy server requires authentication, replace 'username', 'password', 'proxy.server', and 'port' with the appropriate credentials and details.

Remember that using a proxy can help you scrape websites without revealing your real IP address, but you should always make sure that you comply with the terms of service of the website you're scraping and respect robots.txt files.

Also, when doing web scraping, it's essential to be aware of the legal and ethical implications. Ensure that you're not violating any laws or terms of service, and always try to minimize the load you impose on the target website.
