在MySQL中插入数组值

Question

我尝试从empregtable中为emp_no创建数组，并将数组结果存储到另一个表message中(单独的行)。我有类似的代码。但它不起作用。如果有人能在这方面帮我的话，谢谢。

$selectresult = mysqli_query($dbc,"SELECT emp_no FROM empreg"); 
$result_array = array();
while($row = mysqli_fetch_assoc($selectresult))
{
    $result_array[] = $row['emp_no'];
}
$values= serialize($_POST["emp_no"]);
foreach($values as $result)
{
    $sendmessage = mysqli_query ($dbc,"INSERT INTO message (to_user, date,message_title,message_contents) VALUES ('$values', '$date' ,'$subject','$message')");
}

您使用了$values as $result，但又不使用$result。在foreach中将$values更改为$result。

e.g

    $values= serialize($_POST["custom"]);

    foreach($values as $result)
       {
          $sendmessage = mysqli_query ($dbc,"INSERT INTO message (to_user, date,message_title,message_contents) VALUES ('$result', '$date' ,'$subject','$message')");
       }                                                                                                                   ^---- here
