What are some recommended resources or tutorials for learning how to interact with external websites using PHP scripts?

To interact with external websites using PHP scripts, you can use cURL, a library that allows you to make HTTP requests and interact with other websites. You can use cURL to send GET, POST, PUT, DELETE requests, handle cookies, and more. There are also various PHP libraries and frameworks available that can simplify the process of interacting with external websites.

// Example code using cURL to interact with an external website
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://www.example.com/api');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);
curl_close($ch);

// Process the response data
$data = json_decode($response, true);
echo $data['key'];
