请帮我解决下面的数组情况
我有下面的代码，我想问一下，如何根据之前的数据将源插入到其他表中的数据库中？
我从数据库中获取数据并将其显示在复选框上，但是当我检查复选框并按下按钮 Tambah 时，数据被插入到表中，但数据错误，只有 0 和数组。

<?php
$db = new mysqli("localhost","root","","FWS_online");
echo $db->connect_errno?'Koneksi gagal :'.$db->connect_error:'';
$query = ("SELECT * FROM printer_function_commands") or die(mysql_error());
$result = mysqli_query($db, $query);
$pilihan = '';
$data = array();
if (isset($_POST['submit']) && isset($_POST['commands']))
{
if (count($_POST['commands']) > 0)
{
$pilihan = serialize($_POST['commands']);
echo "<p>Data berhasil disimpan ke database berupa ".$pilihan."</p>";
}
}
if ($pilihan <> '')
{
$data = unserialize($pilihan);
}
