php - ios push notification performance -


this php push notification code ios below:

<?php // put device token here (without spaces): $devicetoken = "********************************************";  // put private key's passphrase here: $passphrase = "********";  function pushiosnotification($message)  {    global $devicetoken;    global $passphrase;     $ctx = stream_context_create();     $path = dirname(__file__).'/ck.pem';    //echo $path;     stream_context_set_option($ctx, 'ssl', 'local_cert', $path);    stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase);     // open connection apns server    $fp = stream_socket_client(         'ssl://gateway.sandbox.push.apple.com:2195', $err,         $errstr, 60, stream_client_connect|stream_client_persistent, $ctx);     if (!$fp)         exit("failed connect: $err $errstr" . php_eol);     //echo 'connected apns' . php_eol;     // create payload body    $body['aps'] = array(         'alert' => $message,         'sound' => 'default'         );     // encode payload json    $payload = json_encode($body);     // build binary notification    $msg = chr(0) . pack('n', 32) . pack('h*', $devicetoken) . pack('n', strlen($payload)) . $payload;     // send server    $result = fwrite($fp, $msg, strlen($msg));     if (!$result)         echo 'message not delivered' . php_eol;    else         echo 'message delivered' . php_eol;       // close connection server    fclose($fp); }

this code 1 device,

if need send , support localization,

this code these below.

foreach($devicetokens $devicetoken){    $deviceos = "query device os  memcache";    if($deviceos == "ios")    {        $lang = "query device langauge  memcache";        $message = $messagedata[$lang];        pushiosnotification($devicetoken,$message);     } }

but doubt performance of code, because devicetokens length number of members.
