Question

我试图完成一段我已经工作了一段时间的剧本，而我却无法理解最后一部分。

目前，下面的脚本为我提供了这个输出：

除了每个用户之外，哪个是正确的＆＃39;记录我只有标题行为＆＃34; Mean，Median和Mode＆＃34;。我想要做的是将其设置为获得4个数据列（C，F，I和L）的平均中值和模式。我有标题/标题，但在下面我需要显示配方。因此，在上图中，从MMM行开始到下一个用户的位置，MMM计算应该还有一行，但我无法弄清楚如何对其进行排序。

我可以设置平均中位数和模式公式的变量，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操作，存储当前的rowid编号，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，中位数，模式值

替换

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

与

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

和其他列的等价物

记住要做

$rowNo++;

之后

以便您不会覆盖这些值

基于数组值的计算
