Iphone Push Notification Wrong Device Token - php

Question

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

Assuming your $apns is implemented in this way
$apns = stream_socket_client('ssl://' . $apnsHost . ':' . $apnsPort, $error, $errorString, 2,STREAM_CLIENT_CONNECT, $streamContext);
you should check the $errorString to find out the error.
or try to close the socket for each message and see if there is any difference
fwrite($apns, $apnsMessage);
socket_close($apns);
fclose($apns);
