我正在重新审视这一点，因为我正在处理另一个我想使用相同概念的页面。 此页面显示了我当前从我的 MSSQL 服务器获得的输出。

我有一张我们的活动发生的场地信息表（名称、地址等）。另外，我有一个计划的实际事件表（一个事件可能在一天内和/或多天发生多次）。我通过查询加入这些表（如下所示）。

<?php
try {
    $dbh = new PDO("sqlsrv:Server=localhost;Database=Sermons", "", "");
    $dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    $sql = "SELECT TOP (100) PERCENT dbo.TblSermon.Day, dbo.TblSermon.Date, dbo.TblSermon.Time, dbo.TblSermon.Speaker, dbo.TblSermon.Series, dbo.TblSermon.Sarasota, dbo.TblSermon.NonFlc, dbo.TblJoinSermonLocation.MeetingName, dbo.TblLocation.Location, dbo.TblLocation.Pastors, dbo.TblLocation.Address, dbo.TblLocation.City, dbo.TblLocation.State, dbo.TblLocation.Zip, dbo.TblLocation.Country, dbo.TblLocation.Phone, dbo.TblLocation.Email, dbo.TblLocation.WebAddress
        FROM dbo.TblLocation RIGHT OUTER JOIN dbo.TblJoinSermonLocation ON dbo.TblLocation.ID = dbo.TblJoinSermonLocation.Location RIGHT OUTER JOIN dbo.TblSermon ON dbo.TblJoinSermonLocation.Sermon = dbo.TblSermon.ID
        WHERE (dbo.TblSermon.Date >= { fn NOW() })
        ORDER BY dbo.TblSermon.Date, dbo.TblSermon.Time";
    $stmt = $dbh->prepare($sql);
    $stmt->execute(); 
    $stmt->setFetchMode(PDO::FETCH_ASSOC);
    foreach ($stmt as $row) {
        echo "<pre>";
        print_r($row);
        echo "</pre>";
    }
    unset($row);
    $dbh = null;
}
catch(PDOException $e) {
    echo $e->getMessage();
}
?>

因此，当它遍历查询结果时，它会为每条记录创建一个数组。

我想要做的是以某种方式组合这些数组，以便不会每次都重复场地信息，而是显示每个日期/时间。

我尝试以数组样式输入它，但无法为它找出合适的多维性。我只是粘贴我希望它显示的方式，因为这就是它的最终结果。

它不一定要以那样结束，但它应该很好地了解我在寻找什么。

我不一定要创建一个新数组。我只是不想一遍又一遍地显示相同的信息。

我在想我可以进行某种形式的比较，foreach()其中说的是“如果位置与以前的位置相同”，但我还没有弄清楚如何去做（有没有办法缓存以前的变量做$location1 = [Location], $location2 = [Location], 等等...？

有一点要注意...

这些示例没有不同的扬声器，但有时会有。我希望能够以某种方式访问​​扬声器。我假设我希望它绑定到实际事件。

一种技术：如果你有这样的循环：

while ($row = $query->fetch(PDO::FETCH_NUM) ) {
    list($time,$place,$etc) = $row;
    // display formatted data
}

试试这个：

$row = $query->fetch();
do {
    list($time,$place,$etc) = $row;
    $row = $query->fetch(PDO::FETCH_NUM);
    if ($time != $row[0] && $place != $row[1] && $etc != $row[2]) {
        // display formatted data
    }
} while ($row);

我通常会通过创建一个二维数组来解决这样的问题，该数组按日期然后 ID 进行索引，或者在您的情况下按 ID 然后日期进行索引。

循环遍历事件（第一个维度）并打印出该事件的内容 - 在那里循环遍历该事件的日期并将其打印为列表，如您的示例所示。
