我试图根据从mysql表中检索的列值来获取每个页面上的列值的总和。我正在使用fpdf获取pdf输出。目前它在每个页面上总共提供一列（AMOUNT）。但是在第2页的第一页之后，它正在添加以前的页面值。

如果有人可以帮助我，那么我可以完成我的项目。感谢

Answer 1

phpToPdf是从html文件

生成pdf的好库

使用here

中的此库

在这个库中简单地将html文件添加到phpToPdf函数＆amp;它生成pdf文件＆amp;将其存储在当前目录

Answer 2

在最后的if ($i == $max)块中添加$total = 0;这会将每个页面的总数设置为0，然后开始向其添加金额，并显示正确的价格。

if ($i == $max)
    {
        $pdf->AddPage();

        //print column titles for the current page
        $pdf->SetY(32);
        $pdf->SetX(25);
        $pdf->Cell(30, 6, 'QTY', 1, 0, 'L', 1);
        $pdf->Cell(100, 6, 'PRICE', 1, 0, 'L', 1);
        $pdf->Cell(30, 6, 'AMOUNT', 1, 0, 'R', 1);
        $y_axis=33;
        //Go to next row
        $y_axis = $y_axis + $row_height;

         //Set total to 0 at each new page otherwise it will carry the price offer from the last page
        $total = 0;

        //Set $i variable to 0 (QTY row)
        $i = 0;

    }

每页的列总和
