How can PHP be utilized to interact with external websites and handle user authentication securely?

To interact with external websites and handle user authentication securely in PHP, you can use cURL to make HTTP requests to external APIs and implement secure authentication mechanisms like OAuth or JWT tokens. 

// Example code snippet using cURL to interact with an external website and handle user authentication securely

// Initialize cURL session
$ch = curl_init();

// Set cURL options
curl_setopt($ch, CURLOPT_URL, 'https://api.example.com/endpoint');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Authorization: Bearer YOUR_ACCESS_TOKEN'
));

// Execute cURL request
$response = curl_exec($ch);

// Close cURL session
curl_close($ch);

// Process the response data
echo $response;
