Of course, copy() is the ultimate download function, but it saves the data in a file, and probably
you can use fopen() to get it as a string, but this function double checks everything, and has
support for $http_response_header and
unlike file_get_contents(), it works on php 4.0.0
(Oh, and by the way, if you use it in another function like i do, don't forget to declare
$http_response_header as global, or you won't be able to see the variable, even though you
called it in the function)

"", "https://" => "ssl://",
