推送通知（iOS）未收回/用PHP代码发送

Question

我试图实现APNS（推送通知）。 我已经创建了证书等等。一切都像iv'e一样被创造了许多次。 但我不能从苹果APNS服务器得到一个错误，似乎一切正常，但我仍然没有得到任何推动设备。 这是我用来制作魔法的PHP代码:) 我确保在主机中打开PORTS。

基本上我从数据库获取用户令牌并发送默认声音的推送文本。

有人可以请看看，并告诉我，如果你可以看到这段代码中的任何问题或让我知道我怎么能从APNS服务器获得过程/响应的真实结果？

    $message = $_REQUEST['message']; 

    $sql = "SELECT * FROM `registration` WHERE `chat_id` ='$opponent_id'"; 

    $result = mysql_query($sql); 

    if (!$result) { 
     echo "Could not successfully run query ($sql) from DB: " . mysql_error(); 
     exit;

    if (mysql_num_rows($result) == 0) { 
     echo "No rows found, nothing to print so am exiting"; 
     exit;

，因为你使用的是不返回错误响应简单的二进制格式无法从苹果公司得到的错误响应：

$msg = chr(0) . pack('n', 32) . pack('H*', $token) . pack('n', strlen($payload)) . $payload; 

如果你想，可以返回一个错误响应的格式，您可以使用其中一种增强格式。

例如，以1开始的格式：

味精将与chr(1)开始，随后的4个字节的消息ID的，4个字节的期满时间和所述消息的其余部分将是相同什么你现在pack('n', 32) . pack('H*', $token) . pack('n', strlen($payload)) . $payload

有它应该是这样的：

$msg = chr(1) . pack("N", $msg_id) . pack("N", $expiry) . pack('n', 32) . pack('H*', $token) . pack('n', strlen($payload)) . $payload;
