So I have ran into an issue where a site was using URL's in the file_get_contents function and stopped working on the server. This was also an issue if anyone was trying to do a URL include within a require() or an include(). Here was a solution that I found that worked well with cURL.
function get_content($URL){ $ch = curl_init(); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_URL, $URL); $data = curl_exec($ch); curl_close($ch); return $data; }
