I writing a webapp which uploads images to imgur directly. Since all older version of their APIs have been deprecated i am forced to use v3 of their APIs. Unfortunately I am unable to get the API to work. I am using curl to access the API.

$pvars   = array('image' => base64_encode($data));
$timeout = 30;
$curl    = curl_init();

curl_setopt($curl, CURLOPT_URL, 'https://api.imgur.com/3/upload');
curl_setopt($curl, CURLOPT_TIMEOUT, $timeout);
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, $pvars);
curl_setopt($curl, CURLOPT_HTTPHEADER, array('Authorization: Client-ID xxxxxxa61xxxxxx'));
$xml = curl_exec($curl);
$xmlsimple = new SimpleXMLElement($xml);
print gettype($xml)."<hr>";
echo '<img height="180" src="';
echo $xmlsimple->links->original;
echo '">';
curl_close ($curl);

The "Xml" variable always return as "false", no server error is displayed. Can someone guide me to what I am doing wrong ? Unfortunately I am also unable to find any proper example in the documentation nor around to guide me.
