How to perform a Guzzle request using a specific network interface in PHP?

To perform a Guzzle request using a specific network interface in PHP, you can use the HttpHandlerStack class from the Guzzle library in combination with the soupmix/handler-sockets package.

First, install the necessary dependencies using Composer:

composer require guzzlehttp/guzzle
composer require soupmix/handler-sockets

Then, you can use the following code to perform a Guzzle request using a specific network interface:

use GuzzleHttp\Client;
use GuzzleHttp\HandlerStack;
use GuzzleHttp\Handler\SocksHandler;

$client = new Client([
    'handler' => HandlerStack::create(new SocksHandler('socks://127.0.0.1:9050')),
    'base_uri' => 'http://example.com',
]);

$response = $client->request('GET', '/some-endpoint');

echo $response->getBody();

In this example, we create a new Guzzle Client instance and provide a custom handler option. The custom handler is created using HandlerStack::create() and passing the SocksHandler with the SOCKS proxy address and port (socks://127.0.0.1:9050). Adjust the proxy address and port accordingly. Then, you can make the request using the request() method of the client.

This setup allows you to perform a Guzzle request using a specific network interface in PHP.
