Php查询for循环不能按预期工作

Question

我有以下php脚本查询mysql数据库以发送消息。我想发送每1000行数据库表循环中的“消息”变量。下面是代码，这有什么问题？

<?php 
    $num = $con->query("SELECT gcm_regid from gcm_users")->rowCount(); 
    $current_num = 0; 
    $message = $_POST["message"]; 
    for ($i = 0; $i < $num/999; $i++) { 
     $query = $con->query("SELECT gcm_regid from gcm_users LIMIT $current_num, 999"); 
     foreach ($query as $data) { 
      $row[] = $data["gcm_regid"]; 
     } 
     $pushStatus = send_notification($con, $row, $message); 
     $current_num += 999; 
    } 
?>

检查这个

<?php 
    $num = $con->query("SELECT gcm_regid from gcm_users")->rowCount(); 
    $current_num = 0; 
    $message = $_POST["message"]; 
    for ($i = 0; $i < $num/999; $i++) { 
     $query = $con->query("SELECT gcm_regid from gcm_users LIMIT $current_num, 999"); 
     $row = array() 
     while($result = $query->fetch_assoc()){ 
      $row[] = $result['gcm_regid'] 
     } 
     $pushStatus = send_notification($con, $row, $message); 
     $current_num += 999; 
    } 
?>
