基于数组值的计算

Question

我正在努力完成我已经研究了一段时间的脚本，但我无法弄清楚最后一部分。

目前，下面的脚本给出了这个输出：

这是正确的，除了在每个用户的记录之后，我只有 "Mean, Median and Mode" 的 header 行。我想要做的是将其设置为获取 4 个数据列（C、F、I 和 L）的平均中位数和众数。我有 titles/ 和 headers 但在其下方我需要显示公式。所以在上图中，从 MMM 行到下一个用户的地方，应该还有一行进行 MMM 计算，但我只是不知道如何对其进行排序。

我可以为平均中位数和模式公式设置变量，即使 PHPSpreadsheet 内置了这些公式，但我不太确定如何从每个用户的数组中获取 4 个数据结果并为下一个计算它们行。

有什么想法吗？

Answer 1

作为每个用户的第一个动作，存储当前的rowid号，以便您可以在公式范围内使用它，所以：

foreach($resultData as $idRecords)
{
    $userFirstRow = $rowNo+1;

然后当你需要设置均值、中值、众数时

替换

$sheet->setCellValue("C{$rowNo}", "Mean");

和

$range = 'C'.$userFirstRow.':C'.($rowNo-1);
$sheet->setCellValue("C{$rowNo}", "Mean");
$sheet->setCellValue("C{$rowNo+1}", '=AVERAGE('.$range.')');

和其他列的等效项

记得做

$rowNo++;

之后才不会覆盖这些值
