// Create the payload body
$body['aps'] = array(
    'badge' => +1,
    'alert' => $message,
    'sound' => 'default'
);

$payload = json_encode($body);
// Build the binary notification
$msg = chr(0) . pack('n', 32) . pack('H*', $deviceToken) . pack('n', strlen($payload)) . $payload;

// Send it to the server
$result = fwrite($fp, $msg, strlen($msg));

if (!$result)
    echo 'Message not delivered' . PHP_EOL;
else
    echo 'Message successfully delivered amar' . $message . PHP_EOL;
