file_get_contents does not work on all hosts

[raytiley]

Debugging for someone found their host returned an empty string for file_get_contents. Using curl on there system seemed to work:

Example here: https://stackoverflow.com/a/15617547/160381

$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL, 'url_here');
$result = curl_exec($ch);
curl_close($ch);

$obj = json_decode($result);
echo $obj->access_token;
