Question

我正在尝试使用以下数据将Multidimentional数组排序为15分钟增量，这是来自呼叫中心数据库的电话记录数据

CallID      CallDateTime                    IsLost  IsAnswered

我从MSSQL Server数据库获取，通过以下PHP代码放入数据

 $sql = "SELECT CallID, CallDateTime, IsLost, IsAnswered FROM vwCustomReportingCallsMain WHERE DDI = '2399' AND datediff(day, CallDateTime, '2016-05-10') = 0 ORDER BY CallDateTime ASC";
foreach ($dbh->query($sql) as $row)
    {
        if($row['CallID'] != $last) {
            $callDataArray[] = array("CallID" => $row['CallID'], "CallDateTime" => $row['CallDateTime'], "IsLost" => $row['IsLost'], "IsAnswered" => $row['IsAnswered']);
        }
        $last = $row['CallID'];
    }

所需的输出将类似于以下格式（数据不正确）

Date/Time           IsAnswered IsLost
May 10 2016 08:30   7          0
May 10 2016 09:00   8          0
May 10 2016 09:30   14         0
May 10 2016 10:00   11         0
May 10 2016 10:30   11         0
May 10 2016 11:00   13         0
May 10 2016 11:30   12         0
May 10 2016 12:00   11         0
May 10 2016 12:30   8          0
May 10 2016 13:00   20         0
May 10 2016 13:30   9          0
May 10 2016 14:00   10         0
May 10 2016 14:30   12         0
May 10 2016 15:00   8          0
May 10 2016 15:30   14         0

关于如何在PHP甚至MSSQL PDO中的任何想法？任何帮助都会很棒 - 干杯

Answer 1

这是我将使用的SQL：

SELECT dte = DATEADD(MINUTE, DATEDIFF(MINUTE, 0, CallDateTime) / 15 * 15, 0) AS CallPeriod, SUM(IsAnswered) AS IsAnswered, SUM(IsLost) AS IsLost
FROM vwCustomReportingCallsMain 
WHERE DDI = '2399' AND datediff(day, CallDateTime, '2016-05-10') = 0 
GROUP BY DATEADD(MINUTE, DATEDIFF(MINUTE, 0, CallDateTime) / 15 * 15, 0)
ORDER BY dte ASC;

请注意，我没有可以访问的MS SQL服务器，但它应该非常接近。

Answer 2

这是一个PHP解决方案：

您可以使用以下代码将当前时间四舍五入到最接近的15分钟：

$time = strtotime('May 10 2016 08:55:01:000AM');
$rounded = round($time / (15 * 60)) * (15 * 60);

所以对你来说就像是：

$sql = "SELECT CallID, CallDateTime, IsLost, IsAnswered FROM vwCustomReportingCallsMain WHERE DDI = '2399' AND datediff(day, CallDateTime, '2016-05-10') = 0 ORDER BY CallDateTime ASC";

$callDataArray = array();
foreach ($dbh->query($sql) as $row)
    {
        if($row['CallID'] != $last) {
            $time = strtotime($row['CallDateTime']);
            $date = round($time / (15 * 60)) * (15 * 60);
            if (!isset($callDataArray[$date])) {
                $callDataArray[$date] = array(
                    'isLost' => $row['IsLost'],
                    'isAnswered' => $row['IsAnswered'],
                );
            } else {
                $callDataArray[$date]['isLost'] = $callDataArray[$date]['isLost'] + row['IsLost'];
                $callDataArray[$date]['isAnswered'] = $callDataArray[$date]['isAnswered'] + row['IsAnswered'];
            }
        }
        $last = $row['CallID'];
    }

然后你可以像$callDataArray一样遍历：

<table><tr><th>Date</th><th>Answered</th><th>Lost</th></tr>
<?php
foreach($callDataArray as $date => $data) {
    echo '<tr>';
    echo '<td>' . date('jS \of F Y h:i:s A', $date) . '</td>';
    echo '<td>' . $data['isAnswered'] . '</td>';
    echo '<td>' . $data['isLost'] . '</td>';
    echo '</tr>';
}
?>
</table>

Answer 3

您可以使用以下代码。它可能不完美，但它会让你知道如何进一步。

function roundToNearest30($timestring) {
    $minutes = date('i', $timestring);
    return sprintf("%02d", $minutes - ($minutes % 30));
}

$totalArray = array();
$lastTime = NULL;
foreach($callDataArray as $callData){
    $timeString = strtotime($callData['CallDateTime']);
    $currentHour = date('H', $timeString);
    $nearest30Minutes = roundToNearest30($timeString);
    $nearestTime = "{$currentHour}:{$nearest30Minutes}";

    //create array key based on nearest 30 minutes
    if (!isset($totalArray[$nearestTime])){
        //add the array element as it does not exist
        $totalArray[$nearestTime] = array("TotalLost" => $callData['IsLost'], "TotalAnswered" => $callData['IsAnswered']);
    }else{
        //update they array element with previous data
        $totalArray[$nearestTime]["TotalLost"] += $callData['IsLost'];
        $totalArray[$nearestTime]["TotalAnswered"] += $callData['IsAnswered'];
    }
}

foreach($totalArray as $nearest30 => $data){
    echo "{$nearest30}, Total Lost: {$data['TotalLost']}, Total Answered: {$data['TotalAnswered']}";
    echo "<br>";
}

Output:
08:30, Total Lost: 0, Total Answered: 1
09:00, Total Lost: 0, Total Answered: 6
09:30, Total Lost: 0, Total Answered: 4
10:00, Total Lost: 0, Total Answered: 2
10:30, Total Lost: 0, Total Answered: 5
11:00, Total Lost: 0, Total Answered: 6
11:30, Total Lost: 0, Total Answered: 1
12:00, Total Lost: 0, Total Answered: 1
