如何在 php 变量中包含 php include 语句? [英] How to include a php include statment in a php variable?

问题描述

我有一个包含 html 结构的变量，如下所示:

I have a variable including html structure like following:

$txt = '<table>
           <tr>
               <td>
              </td>
           </tr>
       </table>';

我想在变量中写如下语句:

I want to write the following statement inside the variable :

include_once('./folder/file.php');

我尝试像下面这样写，但失败了:

I try to write it like the following but it failed:

$txt = '<table>
               <tr>
                   <td>';
                   include_once('./folder/file.php');
                  $txt.='</td>
               </tr>
           </table>';

我也这样试过，但还是不行:

And I try it like that and also not work:

$txt = '<table>
                   <tr>
                       <td>
                       {include_once('./folder/file.php');}
                     </td>
                   </tr>
               </table>';

我该怎么做?很抱歉，我对混合 php 和 html 不是很熟练，因此我们将不胜感激 ??

How can I do that? I am sorry not very expert with mixing php and html so a small help will be appreciated ??

推荐答案

使用输出缓冲函数:

ob_start();
include('./folder/file.php');
$include = ob_get_clean();

$txt = '<table>
           <tr>
               <td>' . $include . '</td>
           </tr>
       </table>';

见http://php.net/ob

输出缓冲区收集您发送到浏览器的所有内容，直到您清空、删除或结束它.

The output buffer gathers everything you'd send to the browser until you empty, delete or end it.
