    //get response
    $output = curl_exec($ch);
 
    //Print error if any
    if (curl_errno($ch)) {
        echo 'error:' . curl_error($ch);
    }
 
    curl_close($ch);
}

function sendSMS ($sms) {

  // Set your 46elks API username and API password here
  // You can find them at https://dashboard.46elks.com/
  $username = 'u2c11ef65b429a8e16ccb1f960d02c734';
  $password = 'C0ACCEEC0FAFE879189DD5D57F6EC348';

  $context = stream_context_create(array(
    'http' => array(
      'method' => 'POST',
      'header'  => "Authorization: Basic ".
                   base64_encode($username.':'.$password). "\r\n".
                   "Content-type: application/x-www-form-urlencoded\r\n",
      'content' => http_build_query($sms),
      'timeout' => 10
  )));

  return false !== file_get_contents(
    'https://api.46elks.com/a1/SMS', false, $context );
}


$sms = array(
  'from' => 'DummyFrom',   /* Can be up to 11 alphanumeric characters */
  'to' => '+46400000000',  /* The mobile number you want to send to */
  'message' => 'Hello hello!'
);
sendSMS ($sms);

?>
