我在保存购买详情时收到输出，但结果未存储到数据库中。

您需要按照以下方式进行调试，
答案 1 :(得分：-1)
当您执行INSERT查询时，您无法使用fetch功能，因为它不会返回任何数据。这只能与SELECT一起使用。您需要检查$statement->execute()的结果。
if(isset($_POST["serial_no"]))
{
$connect = new PDO("mysql:host=localhost;dbname=sales", "root", "");
$id = uniqid();
$query = "INSERT INTO elimo_purchase (id,serial_no, e_type, hw_type, sw_type,key)
VALUES (:id,:serial_no, :e_type, :hw_type, :sw_type,:key)";
$statement = $connect->prepare($query);
for($count = 0; $count < count($_POST["serial_no"]); $count++)
{
if (!$statement->execute(
array(
':id' => $id,
':serial_no' => $_POST["serial_no"][$count],
':e_type' => $_POST["e_type"][$count],
':hw_type' => $_POST["hw_type"][$count],
':sw_type' => $_POST["sw_type"][$count],
':key' => $_POST["key"][$count]
)
)) {
die('not ok');
}
}
echo 'ok';
}
