php date_diff如何仅添加那几天的时间

Question

我正在做一个程序，如果您插入excel文件，然后选择人员，然后从excel中显示人员何时上班，何时上班。但是现在我需要把同一天的所有时间加起来。    例如，该人在工作中待了2个小时，然后离开，过了一段时间，他又回来了，现在又呆了5个小时，然后又离开了。    因此，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。但是问题是如何做到的，如果该人说夜班，可以说他在18:00进去，第二天06:00外出。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";
$chosenPerson = $_GET["dla_darbuotojo_pasirinkimas"];
$tmpfname = "visi.xls";
$excelReader = PHPExcel_IOFactory::createReaderForFile($tmpfname);
$excelObj = $excelReader->load($tmpfname);
$worksheet = $excelObj->getSheet(0);
$lastRow = $worksheet->getHighestRow();
$aInT = "Administracija[In]";
$vInT = "Vartai[In]";
$aExT = "Administracija[Exit]";
$vExT = "Vartai[Exit]";
		
$goingIn = false;
$goingExt = false;
$diffFinall = 0;
$goingInValue = 0;
$goingExtValue = 0;

echo "<table>";
for ($row = 1; $row <= $lastRow; $row++) {
    if ($chosenPerson ==  ($worksheet->getCell('D'.$row)->getValue()) ) {
        if (!$goingIn or !$goingExt) {
            //checking if the person alredy went in
            if ((($worksheet->getCell('G'.$row)->getValue()) == $aInT) or (($worksheet->getCell('G'.$row)->getValue()) == $vInT)) {
                //if the person went in
                $goingIn = true;
                echo "<tr><td>";
		    				$goingInValue = $worksheet->getCell('F'.$row)->getValue();
		    				echo $worksheet->getCell('D'.$row)->getValue();
		    				echo "</td><td>";
		    				echo $worksheet->getCell('F'.$row)->getValue();
				    		echo "</td><td>";
						    echo $worksheet->getCell('G'.$row)->getValue();
    						echo "</td><td>";
						
				    		for ($erow= $row +1; ; $erow++){
                    if ($chosenPerson ==  ($worksheet->getCell('D'.$erow)->getValue()) ) {
                        if ((($worksheet->getCell('G'.$erow)->getValue()) == $aExT) or (($worksheet->getCell('G'.$erow)->getValue()) == $vExT)) {
                            $goingExtValue = $worksheet->getCell('F'.$erow)->getValue();
									$goingExt=true;
									
									echo $worksheet->getCell('D'.$erow)->getValue();
									echo "</td><td>";
									echo $worksheet->getCell('F'.$erow)->getValue();
									echo "</td><td>";
									echo $worksheet->getCell('G'.$erow)->getValue();
									echo "</td><td>";
									
									$date1=date_create($goingInValue);
									$date2=date_create($goingExtValue);
									$diff=date_diff($date2,$date1);
									echo $diff->format("%h Val %i Min %s Sek");
									$diffFinall= $diffFinall + $diff;
									echo "</td><tr>";
									$goingIn = false;

									break;
									$row=$erow;
								}
							}							
						}
					}

您的代码很长，我没有数据可以对其进行测试。因此，我制作了一个片段，基本上涵盖了您应该使用的逻辑。

// 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，对其进行多维命名。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);
