Question

I am not sure how to send a push notification to multiple tokens. With my script it seems to only send a push notification to one… as per Apple it would be better to have one open connection and keep it open and send messages when needed. Not sure how to do it on my php server…

$payload['aps'] = array('alert' => "New Cave report for ".$caveName,'badge' => 1, 'sound' => 'default');
$payload['condition'] = array('conditionID' => $ccID, 'caveName' => $caveName);
$payload = json_encode($payload);

// Connection Part
$apnsHost = 'gateway.sandbox.push.apple.com';
$apnsPort = 2195;
$apnsCert = '/var/www/web543/files/apns-dev.pem';

if (!file_exists($apnsCert) )
{
    echo "Certification file not found!";
} else
{
    $streamContext = stream_context_create();
    stream_context_set_option($streamContext,'ssl','local_cert',$apnsCert);

    $apns = stream_socket_client('ssl://' . $apnsHost . ':' . $apnsPort,$error,$errorString,2,STREAM_CLIENT_CONNECT,$streamContext);

    if ( !$apns )
    {
        echo "Connection Failed!".$errorString;
    } else
    {
        $db->query("SELECT DISTINCT token FROM notifications WHERE userID != '{$userID}'");
        if ($db->num_rows()>0) 
        {
            while ($db->next_record())
            {
                $apnsMessage = chr(0) . chr(0) . chr(32) . pack('H*', str_replace(' ', '', $db->f('token'))) . chr(0) . chr(strlen($payload)) . $payload;
                if ( fwrite($apns, $apnsMessage) === FALSE )
                {
                    echo "Can not write";
                }
            }
        }
    }

    fclose($apns);
}

some output of $apnsMessage

Answer 1

Ok. I found the problem.

When compiling as Debug it will send only on the first device when using the DEV certification. If I use Deployment like Ad-Hoc I have to use the Prod Servers and Prod Certificates.

Now everything works.
