我已经检查很多网站我的问题的解决方案，但没有找到合适的解决方案在Excel工作表中插入公式。 我想插入计算学生获得的分数的总和的公式。标记将由教师输入。我已经写入了从数据库和maxmarks插入学生名字后下载excel文件的php代码。 我的excel文件看起来像这样亲切地看到图像，因为我没有10美誉不准我在帖子中插入图片，请点击此链接http://cbsecsnip.in/Capture.JPG 商标列在这里老师会标志的其他数据被获取从数据库空白，百分比列需要一个公式，当老师输入标记时，公式会自动计算标记。填充列和百分比列受到保护。我使用PHPExcel。 这里是PHP代码在产生这个excel文件如何使用phpexcel

如果这些密码在任何情况下都接近实际值，我建议将它们编辑为一些假数据（foo，bar等）。 – Cmorales

@马克·贝克感谢您展示我试着像这样做的方式 -

$calculatRow=''; 
    for($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++; 
}

阅读部分的开发者文档的4.6.4，和例如03formulas.php。

你可以写一个公式，你会写在Excel本身仅储存式前缀与细胞

例如=

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

将写入式=SUM(A10:E9)细胞E10

当写一个公式的单元格，记住：

  • 十进制隔板.（周期）
  • 函数参数分离器是,（逗号）
  • 矩阵行分离器是;（分号）
  • 英文函数名称必须使用

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' 
     ); 
}

谢谢马克您的亲切考虑，但如何更改行号。如果单元格J1包含公式“= SUM（A1：C1）/ 10 + SUM（D1：F1）/ 20 + SUM（G1：I1）/ 60”，那么对于第二行，我需要公式= = SUM（A2 ：C2）/ 10 + SUM（D2：F2）/ 20 + SUM（G2：I2）/ 60 for J2'并重复所有学生在这里我卡住我将如何**更改行号 – user3100533

您动态构建公式....公式字符串只是一个PHP字符串，所以你可以连接它，以及其他任何你可以做的PHP字符串; –

如果您可以通过示例代码片段帮助我，我将非常感激。 – user3100533
