【问题描述】：

我检查了许多网站以解决我的问题，但没有找到合适的解决方案。 我想插入公式来计算学生获得的总分。分数将由老师输入。我已经编写了从数据库和 maxmarks 插入学生姓名后下载 excel 文件的 php 代码。 我的 excel 文件看起来像这样请看图片，因为我没有 10 名声望，我不允许在帖子中插入图片，请点击此链接 http://cbsecsnip.in/Capture.JPG 分数列是空白的，教师将标记从数据库中获取的其他数据，百分比列需要一个公式，该公式将在教师输入分数时自动计算分数。填充列和百分比列受到保护。我使用 PHPExcel。 这是生成此 excel 文件的 php 代码

如果有专家指导我如何做到这一点，我将感谢他们所有人

【问题讨论】：

  • 如果这些密码在任何情况下都接近真实值，我建议将它们编辑为一些虚假数据（foo、bar 等）。
  • 还是本地主机，没人关心

【解决方案1】：

阅读开发者文档的第 4.6.4 节，以及 03formulas.php 等示例。

您可以像在 Excel 中编写公式一样编写公式，只需将前缀为 = 的公式存储在单元格中

例如

$objPHPExcel->getActiveSheet()
    ->setCellValue(
        'E10',
        '=SUM(A10:E9)'
    );

将公式=SUM(A10:E9)写入单元格E10

将公式写入单元格时，请记住：

  • 小数点分隔符为.（句点）
  • 函数参数分隔符为,（逗号）
  • 矩阵行分隔符为;（分号）
  • 必须使用英文函数名

编辑

for ($row = 1; $row <= 10; $row++) {
    $objPHPExcel->getActiveSheet()
        ->setCellValue(
            'J' . $row,
            '=SUM(A'.$row.':C'.$row.')/10 + SUM(D'.$row.':F'.$row.')/20 + SUM(G'.$row.':I'.$row.')/60'
        );
}

【讨论】：

  • 感谢 Mark 的关心，但如何更改行号。就像单元格 J1 包含公式 =SUM(A1:C1)/10 + SUM(D1:F1)/20 + SUM (G1:I1)/60 for cell J1 现在第二行我需要公式 =SUM(A2:C2)/10 + SUM(D2:F2)/20 + SUM (G2:I2)/60 for J2 并在这里为所有学生重复我被卡住了我将如何**更改行号
  • 您动态构建公式......公式字符串只是一个 PHP 字符串，因此您可以连接它，以及您可以执行的任何其他操作来构建 PHP 字符串；
  • 如果您能帮助我提供示例代码 sn-p，我将不胜感激。
  • 不，你问的问题很简单，但我不知道如何进一步简化我的答案
  • @realtebo - 标题为 Locale Settings for Formulae.... 的文档部分在文档的 Word/PDF 版本中查看效果最佳，直到我在降价版本中修复 UTF-8 编码
【解决方案2】：

@Mark Ba​​ker 感谢您展示我这样尝试和完成的方式 -

$calculatRow='';
    for($ctr=0;$ctr < count($marksColumnArr);$ctr++)
    {
    $calculatRow.='(($'.$marksColumnArr[$ctr].'##/$'.$maXmarksColumnArr[$ctr].'$##)*'.$divisionVal[$ctr].')+';      
}
$calculateArrbyRow=substr($calculatRow,0,-1);    
// Replicate formula by row

 for($j=5;$j<count($totalStudents)+5;$j++){
   $formula=str_replace('##',$j,$calculateArrbyRow);
   $cell=PHPExcel_Cell::stringFromColumnIndex($coumnStart+12);
  $objPHPExcel->getActiveSheet()->setCellValue($cell.$j, '='.$formula);
 }    
$coumnStart=($coumnStart-1)+13; $subjectCtr++;
}
