php-GCMPHP发送到设备

关于GCM的问题，要发送信息到所有移动设备中：

PHP:

$resultcoment = mysql_query("SELECT * FROM notificaciones");while ($row = mysql_fetch_array($resultcoment)){$result = '"' . $row['regId'] . '", ';//print_r($result);$registrationIDs = array($result);}$message = $_POST['message'];$fields = array(            'registration_ids'  => $registrationIDs,            'data'              => array( "message" => $message ),            );

结果：

"APA91bHmIHSNCSG_YVHYZMPRrXmw-E_iy7bPA9bo934n67afw8hXJHZvm1MNhrPaRtN6XbkXVjZ9T9YFH9qNi0zM5b9cPGxDhrkhysTXyRwTRLd02lQ- v_e4zWkiGGhQt4BpH_ZLNGGAAU6hWo8ny8Mm2_d7GlEkwcKkZdNhWFO5HXGHWF4gbzM", "APA91bHmIHSNCSG_YVHYZMPRrXmw-E_iy7bPA9bo934n67afw8hXJHZvm1MNhrPaRtN6XbkXVjZ9T9YFH9qNi0zM5b9cPGxDhrkhysTXyRwTRLd02lQ-v_e4zWkiGGhQt4BpH_ZLNGGAAU6hWo8ny8Mm2_d7GlEkwcKkZdNhWFO5HXGHWF4gbzM", "APA91bElWWgUTnoI3YRRunJ_BbaAcdc4PASCB3LxcFWQM9RALQE0hc0c1xVF-EIR7iLYFlbeMDjnMPY-503fqzOPAjJT514zo1j86uhUobhlu79PKtvzjMXiBavoiUcaSKY__JVTbQALvmZ8NJtzzRG81Tf1-svTjw", "APA91bElWWgUTnoI3YRRunJ_BbaAcdc4PASCB3LxcFWQM9RALQE0hc0c1xVF-EIR7iLYFlbeMDjnMPY-503fqzOPAjJT514zo1j86uhUobhlu79PKtvzjMXiBavoiUcaSKY__JVTbQALvmZ8NJtzzRG81Tf1-svTjw", {"multicast_id":8410297698153738741,"success":0,"failure":1,"canonical_ids":0,"results": [{"error":"InvalidRegistration"}]}

怎么会这样？
