PHP与苹果通知网关的socket连接失败

免责声明:on SO我发现了许多类似的问题和一些答案，但没有一个解决我的问题

我有这个简单的PHP代码:

<?php
    $deviceToken = "myDeviceToken";
    $message = "Hello from server";
    $badge = 1;
    $sound = "default";
    // Construct the notification payload
    $body['aps'] = array(
        'alert' => $message
    );
    if ($badge) {
        $body['aps']['badge'] = $badge;
    }
    if ($sound) {
        $body['aps']['sound'] = $sound;
    }
    /* End of Configurable Items */
    $ctx = stream_context_create();
    stream_context_set_option($ctx, 'ssl', 'local_cert', 'my.pem');
    $fp = stream_socket_client("ssl://gateway.sandbox.push.apple.com:2195", $err, $errstr, 60, STREAM_CLIENT_CONNECT, $ctx);
    if (!$fp) {
        print "Failed to connect $err $errstrn";
        return;
    } else {
        print "Connection OK'n";
    }
    $payload = json_encode($body);
    $msg = chr(0) . pack("n", 32) . pack("H*", str_replace(" ", "", $deviceToken)) . pack("n", strlen($payload)) . $payload;
    print "sending message :" . $payload . "'n";
    fwrite($fp, $msg);
    fclose($fp);
?>

当从浏览器调用时，我收到:

[13-12-2011 18:52:52] PHP警告:stream_socket_client() [function. PHP]stream-socket-client]: SSL操作失败，代码1。OpenSSL错误信息:错误:14094410:SSL例程:SSL3_READ_BYTES:sslv3警报握手失败在/home/srv/public_html/myTest.php第28行

知道是怎么回事吗?
