Iphone Push Notification Wrong Device Token

Finally,I found out the sandbox tokens,which were mixed with the production tokens,and I update the code,receive the error response from apple,when post a sandbox token to apple,the next tokens all failed....While the push msg was "$payload['aps'] = array('content-available' => 1); ",apple will push the msg ,but the device will not show this msg,when I find the wrong one,I delete it,and retest.

There is an amusing problem of apple push notification service: when I generate a post notification for my device and send to apple's server,for a while,my device will receive the notification. But if I first post a notification by a wrong devicetoken,then post a right notification to my device,my device will be responseless,just like the push notification was eaten by apple?

What wrong with this?

I use php code for push service,here is the most important part:

$payload['aps'] = array('content-available' => 1);

while ($line = mysql_fetch_array($result, MYSQL_ASSOC)) {

        foreach ($line as $deviceToken) {

            break;

        }



        print_r($deviceToken);

        $apnsMessage = chr(1) . $time . $time . chr(0) . chr(32) . pack('H*', str_replace(' ', '', $deviceToken)) . chr(0) . chr(strlen($payload)) . $payload;

        $ret = fwrite($apns, $apnsMessage);

        if ($ret !== strlen($apnsMessage)) {

            echo "push error";

        }



        ob_flush();

        flush();



        $read = array($apns);

        $null = null;

        $changedStreams = stream_select($read, $null, $null, 0, 100000);//wait for 0.1s



        if ($changedStreams === false) {    

            echo "Error: Unabled to wait for a stream availability";

        } elseif ($changedStreams > 0) {

            print "can't receive any notification behind this token";



            $responseBinary = fread($apns, 6);

            if ($responseBinary !== false || strlen($responseBinary) == 6) {



                $response = unpack('Ccommand/Cstatus_code/Nidentifier', $responseBinary);

                print_r($response);

            }

        } else {

            //update the success push status in database

        }



        print "<br>";

    }

I dont know what's wrong with this,and I have also add feedback service in another php,and get none wrong token from apple,Because I have many devicetoken in my database,I cant find which one of them is wrong.

Someone help me,forgive my poor english
