如何使用phpexcel在Excel中插入公式

php phpexcel
2022-08-30 16:55:07

我已经检查了许多网站以解决问题，但没有找到正确的解决方案。我想插入公式，该公式将计算学生获得的分数总数。成绩将由教师输入。我已经编写了php代码，该代码在从数据库和maxmarks插入学生姓名后下载excel文件。我的excel文件看起来像这样，请看图像，因为我没有10个声誉，我不允许在帖子中插入图像，请按照此链接 http://cbsecsnip.in/Capture.JPG 标记列为空白，教师将标记其他数据是从数据库获取的，百分比列需要一个公式，当教师输入分数时，将自动计算分数。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

如果有任何专家指导我如何做到这一点，我将感谢他们所有人


答案 1

阅读开发人员文档的 4.6.4 节以及类似 .03formulas.php

您可以像在Excel本身中编写公式一样编写公式，只需将前缀公式存储在单元格中即可=

例如：

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

将在单元格中写入公式=SUM(A10:E9)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称

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'
        );
}

答案 2

@Mark贝克 感谢您展示我尝试和完成的方式 -

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