我正在尝试获取如下图所示的输出:
下面是我的表结构和条目:
我尝试过以下查询:
$from_date = '2018-04-01';
$to_date = '2018-09-01';
$cid = mysqli_query($con_db,"SELECT * FROM tbl_silver_stock WHERE stockdate between '$from_date' and '$to_date'");
我在如何检查月份是否完整并获取列的总值方面遇到问题。
请帮助我。
最佳答案
我会将样式和优化留给您。通常，我喜欢用临时值来标识“组”或“批处理”，并在循环数据时滚动记录各列的总和。然而，由于要求和的列太多，我在开发中途改变了主意，决定使用 array_column() 和 array_sum() 。在我看来，这两种技术都可以找到。
就稳定性/安全性而言:
- 在尝试访问值之前，最好先检查预期的提交数据是否存在。
- 还建议对提交的数据进行一定程度的验证。你能走多远取决于你自己。
- 您需要使用准备好的语句，因为允许用户提供的数据不受阻碍地进入查询并不是一个好主意。
- 完成代码的开发/测试后，请务必删除错误消息。您不得让公众看到错误消息，因为它们包含恶意行为者可能利用的有值(value)的详细信息。
测试代码:

$_GET['to'] = '2018-09-18';

DATE_FORMAT(stockdate, '%e-%c-%Y') AS formatteddate,
particulars,

vch_number,

in_price_value,
out_quantity,
out_price_value,
cls_quantity,
cls_price_value
FROM tbl_silver_stock
WHERE stockdate BETWEEN ? AND ?
ORDER BY stockdate, particulars";
if (!$conn = new mysqli(...$config)) {
