php计算foreach循环中2个间隔之间的值

我有以下数组：

    Array

我想检查

log\u date

中的值是否小于下一个

start\u log\u date

。如果较小，则进行计数并继续。我做了一个

foreach

循环，但没有得到我想要的结果

这是我希望显示结果的方式（示例）：

这是我的初始循环：

        $iCount = 1;
    $i = 0;  

    foreach($aRecordsPerDay as $key=>$aRow)
        {

                $aTimeStart[] = strtotime($aRow["start_log_date"]);
                $aTimeStopOld[] = strtotime($sTimeStopOld);

                    if(strtotime($aRow['start_log_date']) < max($aTimeStopOld))
                    {
                      $sTimeStart = $aTimeStart[$i-$iCount];

                      $sTimeStop = $aRow['log_date'];
                      if(strtotime($sTimeStop) < strtotime($sTimeStopOld))
                            $sTimeStop = $sTimeStopOld;
                            $aTimeStop[] = strtotime($sTimeStop);
                            $iCount+=1;
                    }
                    else
                    {

                        if($iCount > 1)
                        {
                            echo "Simultaneous connections".$iCount;

                            $iCount = 1;
                        }
                        else
                        {
                            echo "Simultaneous connections 1";
                            $iCount = 1; 

                        }
                    }


                $sTimeStartOld=$aRow['start_log_date'];
                $sTimeStopOld=$aRow['log_date'];
                $i++;
                ///show data


                }

您可以访问数组的每个项，而无需使用for循环

for($i = 0; $i < $ArrayName.length; $++) {
   if($ArrayName[$i]['log_date'] < $ArrayName[$i+1]['start_log_date']) {
      $count++;
   }
}

（$i=0；$i<$ArrayName.length；$++）的

{
如果（$ArrayName[$i]['log\u date']<$ArrayName[$i+1]['start\u log\u date']））{
$count++；
}
}

如果使用，则应能正常工作

$count=0；
对于（$i=0；$i

您可以对

日期时间对象使用
for
循环：

$count = 0; // initialize counter

for ($i=0; $i < count($array) - 1 ; $i++) { 
    $log_date = new DateTime($array[$i]['log_date']);
    $start_log_date = new DateTime($array[$i+1]['start_log_date']);

    if ($log_date < $start_log_date) {
        $count++;
    } else {
        break;
    }
}

您可以显示循环吗？请显示尝试，以便人们可以帮助您解决问题。如果您的循环看起来像是
foreach（$arr as$key=>$value）
，您现在可以通过
$key+1
轻松访问下一个元素（如果存在！）@h2oooooooo出错了。现在修好了。
for($i = 0; $i < $ArrayName.length; $++) {
   if($ArrayName[$i]['log_date'] < $ArrayName[$i+1]['start_log_date']) {
      $count++;
   }
}

$count = 0;
for ($i = 0; $i < count($array) - 1; ++$i) {
    if (strtotime($array[$i]['log_date']) < strtotime($array[$i + 1]['log_date'])) ++$count;
}

$count = 0; // initialize counter

for ($i=0; $i < count($array) - 1 ; $i++) { 
    $log_date = new DateTime($array[$i]['log_date']);
    $start_log_date = new DateTime($array[$i+1]['start_log_date']);

    if ($log_date < $start_log_date) {
        $count++;
    } else {
        break;
    }
}
