将返回的sql行分割为每两行多个新表行

Question

我目前在一个表中有六个类别列表，我目前使用下面的代码显示。所以下面我显示了所有六个类别和它们中的记录。

我使用相同的代码三次，所以第一组显示前两个类别，第二组显示第三和第四个类别，最后一组代码显示类别五和六。

我想要做的只是一套下面的代码，而不是三个，这将显示我的所有类别与每行两个，而不是我手动不得不改变下面的代码，以适应我添加和删除类别。

我如何去实现这一点，因为我可以做的最好的是让所有的类别出现在一行上，我将如何分割它，所以我可以选择每两个类别去一个新的行，所以我可以有无限的类别出现，而不必改变代码，以适应他们所有的时间？

 $uid = get_current_user_id(); 
     $stn_added_by = ""; 




    echo "<table class='' cellspacing='0' width='100%'><tr>"; 
    $sql3 = mysqli_query($con, "SELECT ID, category FROM knowledgebase_category ORDER BY category LIMIT 2"); 
    while ($row3 = $sql3->fetch_assoc()){ 

    $kbc_ID = $row3['ID']; 
    $kbc_category = $row3['category']; 

    echo "<td width='50%' valign='top'><h4 class='heading'>" . $row3['category']; 
    echo "</h4><br><table class='' cellspacing='0' width='100%'>"; 
    $sql3a = mysqli_query($con, "SELECT kb_ID, kb_subject FROM knowledgebase_items WHERE kb_visible = 'Yes' and kb_category = '$kbc_ID' ORDER BY kb_subject LIMIT 5"); 
    while ($row3a = $sql3a->fetch_assoc()){ 

    echo "<tr><td width='50%'><blockquote class='message'><a class='hover' href='" . $row3a['kb_ID'] . "'>" . $row3a['kb_subject'] . "</a></blockquote></td></tr>"; 
    } 

    echo "<tr><td width='50%'><span class='glyphicon glyphicon-forward' aria-hidden='true'></span> <a class='hover' href='category-" . $kbc_ID . "'>View All Items</a><br><br></td></tr>"; 
    echo "</table>"; 

    echo "</td>"; 
    } 
    echo "</tr></table>"; 








    echo "<table class='' cellspacing='0' width='100%'><tr>"; 
    $sql3 = mysqli_query($con, "SELECT ID, category FROM knowledgebase_category ORDER BY category LIMIT 2,2"); 
    while ($row3 = $sql3->fetch_assoc()){ 

    $kbc_ID = $row3['ID']; 
    $kbc_category = $row3['category']; 

    echo "<td width='50%' valign='top'><h4 class='heading'>" . $row3['category']; 
    echo "</h4><br><table class='' cellspacing='0' width='100%'>"; 
    $sql3a = mysqli_query($con, "SELECT kb_ID, kb_subject FROM knowledgebase_items WHERE kb_visible = 'Yes' and kb_category = '$kbc_ID' ORDER BY kb_subject LIMIT 5"); 
    while ($row3a = $sql3a->fetch_assoc()){ 

    echo "<tr><td width='50%'><blockquote class='message'><a class='hover' href='" . $row3a['kb_ID'] . "'>" . $row3a['kb_subject'] . "</a></blockquote></td></tr>"; 
    } 

    echo "<tr><td width='50%'><span class='glyphicon glyphicon-forward' aria-hidden='true'></span> <a class='hover' href='category-" . $kbc_ID . "'>View All Items</a><br><br></td></tr>"; 
    echo "</table>"; 

    echo "</td>"; 
    } 
    echo "</tr></table>"; 







    echo "<table class='' cellspacing='0' width='100%'><tr>"; 
    $sql3 = mysqli_query($con, "SELECT ID, category FROM knowledgebase_category ORDER BY category LIMIT 4,2"); 
    while ($row3 = $sql3->fetch_assoc()){ 

    $kbc_ID = $row3['ID']; 
    $kbc_category = $row3['category']; 

    echo "<td width='50%' valign='top'><h4 class='heading'>" . $row3['category']; 
    echo "</h4><br><table class='' cellspacing='0' width='100%'>"; 
    $sql3a = mysqli_query($con, "SELECT kb_ID, kb_subject FROM knowledgebase_items WHERE kb_visible = 'Yes' and kb_category = '$kbc_ID' ORDER BY kb_subject LIMIT 5"); 
    while ($row3a = $sql3a->fetch_assoc()){ 

    echo "<tr><td width='50%'><blockquote class='message'><a class='hover' href='" . $row3a['kb_ID'] . "'>" . $row3a['kb_subject'] . "</a></blockquote></td></tr>"; 
    } 

    echo "<tr><td width='50%'><span class='glyphicon glyphicon-forward' aria-hidden='true'></span> <a class='hover' href='category-" . $kbc_ID . "'>View All Items</a><br><br></td></tr>"; 
    echo "</table>"; 

    echo "</td>"; 
    } 
    echo "</tr></table>"; 

下面是我的网站上面的代码的样子。

感谢

尝试这一个，使用2周的div 50％的宽度，按您的设计在未来，如果你需要3或4列，您可以调整。并没有必要甚至没有类别？!!

//显示所有类别和两个类别拆分到各行

echo "<div class='' cellspacing='0' width='100%'>"; 
$sql3 = mysqli_query($con, "SELECT ID, category FROM knowledgebase_category ORDER BY category"); 
while ($row3 = $sql3->fetch_assoc()){ 

            $kbc_ID = $row3['ID']; 
            $kbc_category = $row3['category']; 

            echo "<div width='50%' valign='top' style='float:left;'><h4 class='heading'>" . $row3['category'] . "</h4>"; 

             echo "<table class='' cellspacing='0' width='100%'>"; 
              $sql3a = mysqli_query($con, "SELECT kb_ID, kb_subject FROM knowledgebase_items WHERE kb_visible = 'Yes' and kb_category = '$kbc_ID' ORDER BY kb_subject LIMIT 5"); 
              while ($row3a = $sql3a->fetch_assoc()){ 
               echo "<tr><td width='50%'><blockquote class='message'><a class='hover' href='" . $row3a['kb_ID'] . "'>" . $row3a['kb_subject'] . "</a></blockquote></td></tr>"; 
              } 
               echo "<tr><td width='50%'><span class='glyphicon glyphicon-forward' aria-hidden='true'></span> <a class='hover' href='category-" . $kbc_ID . "'>View All Items</a><br><br></td></tr>"; 
             echo "</table>"; 

            echo "</div>"; 
} 
echo "</div>";
