$ch = curl_init();

//Set curl to return the data instead of printing it to the browser.
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// Personally I prefer CURLAUTH_ANY as it covers all bases
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
// This is occassionally required to stop CURL from verifying the peer’s certificate.
// CURLOPT_SSL_VERIFYHOST may also need to be TRUE or FALSE if
// CURLOPT_SSL_VERIFYPEER is disabled (it defaults to 2 – check the existence of a
// common name and also verify that it matches the hostname provided)
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
//Set the URL
curl_setopt($ch, CURLOPT_URL, $url);
//Execute the fetch
$data = curl_exec($ch);
//Close the connection
curl_close($ch);
