What best practices should be followed when attempting to access user data from external websites using PHP?

When accessing user data from external websites using PHP, it is important to follow best practices to ensure security and reliability. One key practice is to always validate and sanitize user input to prevent injection attacks. Additionally, consider using secure communication protocols like HTTPS to protect data in transit. Lastly, make sure to handle errors gracefully and securely store any sensitive data. 

// Example code snippet for accessing user data from an external website in PHP

$url = 'https://example.com/api/user_data';
$ch = curl_init($url);

// Set options for the cURL request
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // Disable SSL verification for simplicity

$response = curl_exec($ch);

if($response === false){
    // Handle error
    echo 'Error: ' . curl_error($ch);
} else {
    // Process the response data
    $userData = json_decode($response, true);
    
    // Use the user data as needed
    var_dump($userData);
}

curl_close($ch);
