各位

我想在三张桌子上做一个连接。下面是完成此任务的代码：

$query = "SELECT Distinct ID, Date, SC_LName, SC_FName, Activity_Type, Hours, Pay_Rate, PT_First_Name, PT_Last_Name
FROM Payroll
LEFT OUTER JOIN Plans ON Plans.Client_ID = Payroll.Client_ID
GROUP BY STR_TO_DATE( DATE,  '%m/%d/%Y' ), Payroll.SC_LName";

$res = mysqli_query($con, $query);
查询之后，我在while循环中有一个for循环，如下所示：

while ($row = mysqli_fetch_assoc($res)) {
    $daterange = $row['Approval_Date'];
    $m30 = date('m/d/Y',strtotime('+ 30 days', strtotime($daterange)));
    $m60 = date('m/d/Y',strtotime('+ 60 days', strtotime($daterange)));
    $m90 = date('m/d/Y',strtotime('+ 90 days', strtotime($daterange)));
    $m120 = date('m/d/Y',strtotime('+ 120 days', strtotime($daterange)));
    $m150 = date('m/d/Y',strtotime('+ 150 days', strtotime($daterange)));
    $m180 = date('m/d/Y',strtotime('+ 190 days', strtotime($daterange)));
    $m210 = date('m/d/Y',strtotime('+ 210 days', strtotime($daterange)));
    $m240 = date('m/d/Y',strtotime('+ 240 days', strtotime($daterange)));
    $m270 = date('m/d/Y',strtotime('+ 270 days', strtotime($daterange)));
    $m300 = date('m/d/Y',strtotime('+ 300 days', strtotime($daterange)));
    $m330 = date('m/d/Y',strtotime('+ 330 days', strtotime($daterange)));
    $m360 = date('m/d/Y',strtotime('+ 360 days', strtotime($daterange)));

    $Hourly_Pay = round($row['Pay_Rate'] * $row['Hours'],2);
    asort($row);
    foreach($row as $key => $val) {
        $time = strtotime($val);
        $newformat = date('Y-m-d',$time);
        $myformat = date('Y-m-d', strtotime($row['Date']));
            if ( $time > strtotime("01/28/2015") 
              AND $time < strtotime("03/31/2015") 
              AND $key <> "Date" 
              AND $myformat = $newformat) {
                 echo "<tr><td>" . $row['Date'];  
                 echo "</td><td>"; 
                 if (strtotime($row['Date']) < strtotime($m30)) {
                        echo "30 Day";
                 }; 
                 if (strtotime($row['Date']) > strtotime($m60) 
                    AND strtotime($row['Date']) < strtotime($m90)) {
                        echo "60 Day";
                 }; 
                 if (strtotime($row['Date']) > strtotime($m90) 
                    AND strtotime($row['Date']) < strtotime($m120)) {
                       echo "90-Day";
                 }; 
                 if (strtotime($row['Date']) > strtotime($m120) 
                    AND strtotime($row['Date']) < strtotime($m150)) {
                       echo "210 Day";
                 }; 
                 if (strtotime($row['Date']) > strtotime($m150) 
                    AND strtotime($row['Date']) < strtotime($m180)) {
                       echo "150-Day";
                 }; 
                 if (strtotime($row['Date']) > strtotime($m180) 
                    AND strtotime($row['Date']) < strtotime($m210)) {
                       echo "180-Day";
                 }; 
                 if (strtotime($row['Date']) > strtotime($m210) 
                     AND strtotime($row['Date']) < strtotime($m240)) {
                       echo "210 Day";
                 }; 
                 echo "</td><td>"  . $row['SC_LName'] . "</td><td>" 
                    . $row['SC_FName'] . "</td><td>" . $row['Title'] 
                    . "</td><td>" . $row['PT_Last_Name'] . "</td><td>" 
                    . $row['PT_First_Name'] . "</td><td>" 
                    . $row['Activity_Type'] . "</td><td>" 
                    . $row['Hours'] . "</td><td>" 
                    . $row['Pay_Rate'] . "</td><td>" 
                    . $Hourly_Pay .  "</td><td>" 
                    . $row['Budget_Amt'] . "</td><td>" 
                    . $row['Notes'] . "</td></tr>";
              }
      }
}
我将我的IF语句改为：

if ( $time > strtotime("01/28/2015") AND $time < strtotime("03/31/2015") AND $key == "Date" AND $myformat = $newformat) {echo "<tr><td>" . $row['Date'];  echo "</td><td>"; if (strtotime($row['Date']) < strtotime($m30)) {echo "30 Day";}; if (strtotime($row['Date']) > strtotime($m60) AND strtotime($row['Date']) < strtotime($m90)) {echo "60 Day";}; if (strtotime($row['Date']) > strtotime($m90) AND strtotime($row['Date']) < strtotime($m120)) {echo "90-Day";}; if (strtotime($row['Date']) > strtotime($m120) AND strtotime($row['Date']) < strtotime($m150)) {echo "210 Day";}; if (strtotime($row['Date']) > strtotime($m150) AND strtotime($row['Date']) < strtotime($m180)) {echo "150-Day";}; if (strtotime($row['Date']) > strtotime($m180) AND strtotime($row['Date']) < strtotime($m210)) {echo "180-Day";}; if (strtotime($row['Date']) > strtotime($m210) AND strtotime($row['Date']) < strtotime($m240)) {echo "210 Day";}; echo "</td><td>"  . $row['SC_LName'] .

if ( $time > strtotime("01/28/2015") AND $time < strtotime("03/31/2015") AND $key == "Date" AND $myformat = $newformat) {echo "<tr><td>" . $row['Date'];  echo "</td><td>"; if (strtotime($row['Date']) < strtotime($m30)) {echo "30 Day";}; if (strtotime($row['Date']) > strtotime($m60) AND strtotime($row['Date']) < strtotime($m90)) {echo "60 Day";}; if (strtotime($row['Date']) > strtotime($m90) AND strtotime($row['Date']) < strtotime($m120)) {echo "90-Day";}; if (strtotime($row['Date']) > strtotime($m120) AND strtotime($row['Date']) < strtotime($m150)) {echo "210 Day";}; if (strtotime($row['Date']) > strtotime($m150) AND strtotime($row['Date']) < strtotime($m180)) {echo "150-Day";}; if (strtotime($row['Date']) > strtotime($m180) AND strtotime($row['Date']) < strtotime($m210)) {echo "180-Day";}; if (strtotime($row['Date']) > strtotime($m210) AND strtotime($row['Date']) < strtotime($m240)) {echo "210 Day";}; echo "</td><td>"  . $row['SC_LName'] .

"</td><td>" . $row['Pay_Rate'] . "</td><td>" . $Hourly_Pay .  "</td><td>" . $row['Budget_Amt'] . "</td><td>" . $row['Notes'] . "</td></tr>";

if（$time>strottime（“01/28/2015”）和$timestrottime（$m60）和strottime（$row['Date m90））{echo“60天”；}；if（strotime（$row['Date']）>strotime（$m90）和strotime（$row['Date']）strotime（$m120）和strotime（$row['Date']）strotime（$m180）和strotime（$row['Date']）
总而言之，这两个更改为我提供了正确的行数。我对键/日期配对做了一些错误，并使连接变得过于复杂。

我怀疑您看到重复行的原因是因为您在SELECT子句中包含ID和PT_Last_Name，但从未在输出中使用它

您可能想顺道来看看，征求一些关于如何更好地构建代码的建议。

基于我在这里得到的慷慨帮助，我找到了解决方案。：）

我将查询更改为：

$query = "SELECT * from Plans
LEFT OUTER JOIN Payroll ON Payroll.Client_ID = Plans.Client_ID";

$query = "SELECT * from Plans
LEFT OUTER JOIN Payroll ON Payroll.Client_ID = Plans.Client_ID";
我将我的IF语句改为：

if ( $time > strtotime("01/28/2015") AND $time < strtotime("03/31/2015") AND $key == "Date" AND $myformat = $newformat) {echo "<tr><td>" . $row['Date'];  echo "</td><td>"; if (strtotime($row['Date']) < strtotime($m30)) {echo "30 Day";}; if (strtotime($row['Date']) > strtotime($m60) AND strtotime($row['Date']) < strtotime($m90)) {echo "60 Day";}; if (strtotime($row['Date']) > strtotime($m90) AND strtotime($row['Date']) < strtotime($m120)) {echo "90-Day";}; if (strtotime($row['Date']) > strtotime($m120) AND strtotime($row['Date']) < strtotime($m150)) {echo "210 Day";}; if (strtotime($row['Date']) > strtotime($m150) AND strtotime($row['Date']) < strtotime($m180)) {echo "150-Day";}; if (strtotime($row['Date']) > strtotime($m180) AND strtotime($row['Date']) < strtotime($m210)) {echo "180-Day";}; if (strtotime($row['Date']) > strtotime($m210) AND strtotime($row['Date']) < strtotime($m240)) {echo "210 Day";}; echo "</td><td>"  . $row['SC_LName'] .

你确定所有日期都是相同的吗？你可能会在小时/分钟/秒上失去一些时间精度。谢谢你的回复，Clement.）日期字段仅限于当天，因此我不认为小时、分钟或秒会导致重复。首先，确保这不是数据库查询的问题。CBroe：我在phpmyadmin中运行了查询，并且得到了合理的结果。没有重复。很难说，但我建议您创建一个新的测试页nd将您的PHP简化为一个或两个条件语句。原因显然在那里，而不是查询本身。一旦确定了原因，您就可以慢慢地开始添加其他条件语句。我会尝试将
foreach
置于
while
循环之外，看看会发生什么。祝您好运。谢谢。：）我实际上重写了查询和一些代码。我认为它现在可以工作了。我需要更新或关闭它或其他什么。不过，我会发布解决方案，供其他人查看。
