ios 消息推送，php做推送服务端。服务端代码如下
<?php
// 得到deviceToken
$deviceToken = 'c3d475905aafdf800ddfce96973efa4679bc87ab2c';
// 密钥:
$passphrase = 'pass123';
// 要推送的消息:
$message = 'My first push test!';
//默认声音
$sound = 'default';
$ctx = stream_context_create();
// ck.pem文件 由ios提供
stream_context_set_option($ctx, 'ssl', 'local_cert', 'ck.pem');
stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase);
// 打开一个连接到apns服务器
$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;
$body['aps'] = array(
'alert' => $message,
'sound' => 'default',
"badge" => $count
);
// 转换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);   
?>
