我有以下用于 ios 推送通知的 php 代码。这里我使用 fwrite() 部分中的循环为 2 个设备编写代码。当前代码工作正常。我的疑问是，我可以在不使用 for 循环的情况下直接传递设备令牌数组吗？
<?php
// Put your device token here (without spaces):
$deviceToken[0] = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';
$deviceToken[1] = 'yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy';
// Put your private key's passphrase here:
$passphrase = '123456';
// Put your alert message here:
$message = 'multiple device push notification...!';
////////////////////////////////////////////////////////////////////////////////
$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert', 'abc.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',
'badge' => '+1'
);
// Encode the payload as JSON
$payload = json_encode($body);
for($i=0;$i<2;$i++)
{
// Build the binary notification
$msg = chr(0) . pack('n', 32) . pack('H*', $deviceToken[$i]) . pack('n', strlen($payload)) . $payload;
// Send it to the server
$result = fwrite($fp, $msg, strlen($msg));
echo "msg may be delivered";
}
if (!$result)
echo 'Message not delivered' . PHP_EOL;
else
echo 'Message successfully delivered' . PHP_EOL;
// Close the connection to the server
fclose($fp);
