Question

我试图从mysql提取的返回数据中获取此输出：

 <table>
     <thead>
        <tr>
         <th></th><th><img src='img1.jpg'></th><th><img src='img2.jpg'></th>
        </tr>
     </thead>
     <tbody>
        <tr>
          <td colspan='5'>Features</td>
          <td>LCD</td><td>Yes</td><td>No</td>
          <td>Auto Pilot</td><td>No</td><td>No</td>
          <td>Fast Generation</td><td>Yes</td><td>No</td>
          <td>Dual Cores</td><td>No</td><td>Yes</td>
        </tr>
     </tbody>
   </table>

但是我无法通过一个foreach循环获得以下代码来实现该输出。它使用in_array来检查返回的数据中是否存在$ featured_tests中的每个值。

  $featured_tests = array("LCD","Auto Pilot","Fast Generation","Dual Cores");
  $table_head ="<table><thead><tr><th></th>";
  $table_colspan1 = "</tr></thead><tbody><tr><td colspan='5'>Features</td></tr>";
  $table_end ="</tr></tbody></table>";

    foreach($rows as $row) 
    {
      $special_features = explode(",",$row->special_features);
      $header_image .= "<th><img src='".$row->image_url."'></th>";
      foreach($featured_tests as $featured_test)
      {
        $featured .= "<tr><td>".$featured_test."</td>";

        if(in_array($featured_test,$special_features))
        {
          $featured .= "<td>Yes</td>";
        }
        else
        {
          $featured .= "<td>No</td>";
        }    
      }
   }


 $table_html = $table_head.$header_image.$table_colspan1.$featured.$table_end;

但我得到的结果是一团糟。 $featured_tests中的每个值都会针对每个产品反复迭代，从而产生一个非常长的表。任何人都可以帮我纠正我的代码以获得理想的输出吗？

结果如下：

 <table>
     <thead>
        <tr>
         <th></th><th><img src='img1.jpg'></th><th><img src='img2.jpg'></th>
        </tr>
     </thead>
     <tbody>
        <tr>
          <td colspan='5'>Features</td>
        </tr>
        <tr>
          <td>LCD</td><td>Yes</td>
        </tr>
        <tr>
          <td>Auto Pilot</td>No<td></td>
        </tr>
        <tr>
          <td>Fast Generation</td><td>Yes</td>
        </tr>  
        <tr>         
          <td>Dual Cores</td>No<td>
        </tr>
        <tr>
          <td>LCD</td><td>No</td>
        </tr>
        <tr>
          <td>Auto Pilot</td>No<td></td>
        </tr>
        <tr>
          <td>Fast Generation</td><td>No</td>
        </tr>  
        <tr>         
          <td>Dual Cores</td>Yes<td>
        </tr>
     </tbody>
   </table>

你正在最深刻的foreach中创建新行<tr> ...

以这个例子来制作你想要的东西：

<table>
    <thead>
        <th>Col 1</th><th>Col 2</th>
    </thead>
    <tbody>
        <?php foreach($large_array as $less_array): ?>
            <tr>
            <?php foreach($less_array as $row): ?>
                <!-- <td> contents etc</td>-->
            <?php endforeach?>
            </tr>
       <?php endforeach;?>
    </tbody>
</table>

foreach循环不生成正确的html表
