What are some best practices for securely accessing and reading content from external websites in PHP?

When accessing and reading content from external websites in PHP, it is important to follow best practices to ensure security. One way to do this is by using the cURL library, which provides a way to make HTTP requests and handle responses securely. By setting appropriate options and validating the response, you can help prevent security vulnerabilities such as injection attacks or data leaks. 

$url = 'https://www.example.com/api/data';
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
$response = curl_exec($ch);

if($response === false){
    die('Error: ' . curl_error($ch));
}

curl_close($ch);

// Process the response data securely
