php date_diff 如何只加那几天的小时数

Question

我正在做一个程序，你插入 excel 文件，然后你选择人，然后从 excel 中显示这个人什么时候上班，什么时候出去。但是现在我需要把同一天的所有小时加起来。例如，这个人在工作中待了 2 个小时，然后他离开了，过了一段时间他又回来了，现在他又待了 5 个小时，然后又离开了。所以现在我需要程序能够识别上一个和下一个日期是否相同。如果它们相同，则将它们加起来。但问题是如何去做，如果这个人说夜班结束，让我们说他在 18:00 进去，第二天 06:00 出去。所以这些时间必须分开。有人有什么想法吗？

到目前为止的代码：

table tr td {
  border: 1px solid black;
}

table {
  border: 1px solid black;
}

<?php
error_reporting(0); //disable all errors and notices
require_once "Classes/PHPExcel.php";

$tmpfname = "visi.xls";
$excelReader = PHPExcel_IOFactory::createReaderForFile($tmpfname);
$excelObj = $excelReader->load($tmpfname);
$worksheet = $excelObj->getSheet(0);
$lastRow = $worksheet->getHighestRow();

for ($row = 1; $row <= $lastRow; $row++) {
    if ($chosenPerson ==  ($worksheet->getCell('D'.$row)->getValue()) ) {

            //checking if the person alredy went in
            if ((($worksheet->getCell('G'.$row)->getValue()) == $aInT) or (($worksheet->getCell('G'.$row)->getValue()) == $vInT)) {

你的代码比较长，我没有数据来测试。所以我做了一个片段，基本上涵盖了你应该使用的逻辑。

// Define total hours before.
$totalHours = 0;

// Imaginary loop {

/**
 *  B and E are th columns 
 *  should be replaced with $worksheet->getCell('B'.$erow)->getValue()
*/
$B = '2018-12-04 07:44:56';
$E = '2018-12-04 18:52:31';

$B = strtotime($B);
$E = strtotime($E);

// this total hours could be part of a multi dimensional array
// it keeps adding up because of this: +=
$totalHours += ($E-$B)/60/60;

// } End Imaginary Loop

echo $totalHours;

您可以使用 $chosenPerson 作为数组中的键将其命名为多维。像这样：

$totalHours = array();

// in the loop:
if (!isset($totalHours[$chosenPerson]))
    $totalHours[$chosenPerson] = ($E-$B)/60/60;
else
    $totalHours[$chosenPerson] += ($E-$B)/60/60;
// end of loop

var_dump($totalHours);
