function curlPost($url, $headers, $username, $password, $data) {
     $ch = curl_init();
     curl_setopt($ch, CURLOPT_URL, $url);
     curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
     curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
     curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
     curl_setopt($ch, CURLINFO_HEADER_OUT, true);
     curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
     curl_setopt($ch, CURLOPT_USERPWD, $username . ":" . $password);
     curl_setopt($ch, CURLOPT_TIMEOUT, 30);
     curl_setopt($ch, CURLOPT_POST, 1);
     curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
     curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
     return curl_exec($ch);
     curl_close($ch);

$url = 'https://SERVERNAME/ocs/v2.php/apps/files_sharing/api/v1/shares';
$headers = Array('OCS-APIRequest: true');
$username = 'NEXTCLOUDUSERNAME';
$password = 'NEXTCLOUDPASSWORD';
$data = 'path=PATH/FILE.xxx&shareType=3&permissions=1&format=json';
echo curlPost($url, $headers, $username, $password, $data);
