How can PHP developers handle dependencies like Guzzle for HTTP requests when limited to a shared hosting environment without command line access?

When limited to a shared hosting environment without command line access, PHP developers can manually install Guzzle by downloading the library and including it in their project directory. They can then require the Guzzle autoload file in their PHP script to use the library for making HTTP requests.

// Download Guzzle library and place it in your project directory
// Include the Guzzle autoload file
require 'path/to/guzzle/autoload.php';

// Now you can use Guzzle for making HTTP requests
$client = new GuzzleHttp\Client();
$response = $client->request('GET', 'https://api.example.com');
echo $response->getBody();
