向多個設備發送推送消息

Question

根據一篇文章，作者在下面提供了一個PHP腳本來向一個設備發送推送消息（$ deviceToken）。我如何才能將推送消息發送給多個設備而不是一個設備？

<?php 

// Put your device token here (without spaces): 
$deviceToken = 'de641706f194fa32169dcd8297309153bb6b4de838f9b7cb7cb83c0e24b6609b'; 

// Put your private key's passphrase here: 
$passphrase = 'ibpspass'; 

// Put your alert message here: 
$message = 'New promotion is updated!'; 

//////////////////////////////////////////////////////////////////////////////// 

$ctx = stream_context_create(); 
stream_context_set_option($ctx, 'ssl', 'local_cert', 'ck.pem'); 
stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase); 

// Open a connection to the 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 to connect: $err $errstr" . PHP_EOL); 

echo 'Connected to APNS' . PHP_EOL; 

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

// Encode the payload as JSON 
$payload = json_encode($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' . PHP_EOL; 

// Close the connection to the server 
fclose($fp);

您需要維護設備數據庫，並將通知發送給每個設備。這就是爲什麼API設計用於大容量，小尺寸的消息。
