$ch = curl_init();
$options = array(CURLOPT_URL => 'http://your/server/api/upload',

CURLOPT_HEADER => true, //Return header
CURLOPT_SSL_VERIFYPEER => false, //Don't veryify server certificate
CURLOPT_POST => true,
CURLOPT_POSTFIELDS => $data
);
curl_setopt_array($ch, $options);
$result = curl_exec($ch);
$header_info = curl_getinfo($ch,CURLINFO_HEADER_OUT);
$header_size = curl_getinfo($ch, CURLINFO_HEADER_SIZE);
$header = substr($result, 0, $header_size);
$body = substr($result, $header_size);
