Question

我有2列，包含6个项目

column A  column B
a         200
a         300
a         300
b         600
b         200
b         500

当我在html表中获取列时，我希望它表示如下：

column A column B column C column D
a        200      300      300 
b        600      200      500

使用普通的php和mysql

请任何1给我解决方案吗？

Answer 1

1）SELECT colA, colB FROM your_table

2）将数据保存在关联数组中;

   $colAdata=array();
   $colBdata=array();

   foreach ($results as $r) {
     if ($r["colA"]=="a")
          $colAdata[] = $r;
     else
          $colBdata[] = $r;
    }

3）根据它们对应的col打印：

    echo "<table>";

    echo "<tr>";
    echo "<td>A</td>";
    foreach ($colAdata as $r)
           echo "<td>".$r["colB"]."</td>";
    echo "</tr>";

    echo "<tr>";
    echo "<td>B</td>";
    foreach ($colBdata as $r)
           echo "<td>".$r["colB"]."</td>";

    echo "</tr>";

    echo "</table>";

2）

   foreach ($results as $r) {
          $item = $r["colA"];

          if (!isset($coldata[$item])
              $coldata[ $item ] = $r;
    }

3）

    $possibilities=array_keys($coldata);

    foreach ($possibilities as $p) {
       echo "<tr>";
       echo "<td>$p</td>";
       foreach ($coldata[$p] as $r)
              echo "<td>".$r["colB"]."</td>";
       echo "</tr>";
    }

6行，2列，使用php和mysql显示为2行和4列
