Question

否，我正在计算总余额amt（$ row ['Bal‌anceAmt']）。在此另一个字段中，有发票编号。发票编号将是重复的。如果重复出现，则一次只能计算余额。例如，发票数字为1,1,2,3,4,4,7，余额为10,10,30,40,20,20,80，总余额应为20 + 30 + 20 + 80 = 15 现在的问题是，计算所有余额也包括所有重复的发票编号有什么办法可以消除此错误？

 $sql = "SELECT a.cusName as CustomerName, a.invoiceNo as InvoiceNo,
                a.bal_amt as BalanceAmt,
                b.itemsName as Items,b.rate as Rate,
                ROUND(b.amt_vat + b.amount, 2) as Amount
                FROM invoices a, invoice_items b where a.invoiceID=b.invoiceid and a.status IS NULL
                and a.invoiceDate between '$getfromdate' and '$gettodate' 
                order by a.invoiceID desc";

  $result = mysqli_query($link, $sql);
  $resultpaymenttotal = mysqli_query($link, $sqlgettotalpyment);

尝试一下：

初始化后立即const staticID = "9B60F750-C64F-433A-8C1E-9E88639DC503"; onLoad(object) { object.uuid = staticID; }添加$tot_BalanceAmt = 0;
放入 while循环代码字符串的正文：

$invoiceHasProcessed = array();

替换为

$tot_BalanceAmt += $row['BalanceAmt'];

如何通过使用Excel工作表中的PHP删除重复的ID来计算列值的总和？
