Php 推送IOS 這段代碼有問題嗎？
大家看下 這個代碼 對不對？

function tuisong(){
//手機註冊應用返回唯一的deviceToken   
$deviceToken = '7146a15ef9e1ebb8122c110e6fc970a454db3a9946ce24402481a564ee900e'; 
$deviceToken = $deviceToken; 
//ck.pem通關密碼   
$pass = 'yeyu';     //$pass = '123456';   
//訊息內容   
$message = 'zao shang  hao!';  
//badge我也不知是什麼   
$badge = 4;  
//sound我也不知是什麼（或許是推送訊息到手機時的提示音）   
$sound = 'Duck.wav';  
//建設的通知有效載荷（即通知包含的一些資訊）   
$body = array();  
//$body['id'] = "4f94d38e7d9704f15c000055";  
$body['aps'] = array('alert' => $message,'issystem'=>1);

//把數組資料轉換為json資料   
$payload = json_encode($body);  
print_r($payload);
//echo strlen($payload),"\r\n";  
  
//下邊的寫法就是死寫法了，一般不需要修改，   
//唯一要修改的就是：ssl://gateway.sandbox.push.apple.com:2195這個是沙箱測試地址，ssl://gateway.push.apple.com:2195正式發布地址   

$apnscert=$_SERVER['DOCUMENT_ROOT'].'data/ck.pem';
print_r($apnscert);
$ctx = stream_context_create();  
var_dump($ctx);
//stream_context_set_option($ctx, 'ssl', 'local_cert', 'ck.pem');  
stream_context_set_option($ctx, 'ssl', 'local_cert', $apnscert);

$fp = stream_socket_client('ssl://gateway.push.apple.com:2195', $err, $errstr, 60, STREAM_CLIENT_CONNECT, $ctx);  
//var_dump($fp);
if (!$fp) {  
print "Failed to connect $err $errstr\n";  
return;  
}  
else {  
   //print "Connection OK\n
";  
}  
// send message  (群發要迴圈)
$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); 
}
