How can PHP developers securely download files from password-protected servers using HTTP?

To securely download files from password-protected servers using HTTP in PHP, you can use the cURL library to send an HTTP request with the appropriate credentials. You will need to set the CURLOPT_USERPWD option to include the username and password for authentication. This will allow you to access the protected server and download files securely. 

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://example.com/file.zip');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERPWD, 'username:password');
$data = curl_exec($ch);
curl_close($ch);

file_put_contents('downloaded_file.zip', $data);
