在输出用户消息后重定向PHP页面 [英] Redirect PHP page AFTER outputting user message

问题描述

我试图在成功执行后重定向页面。但是，我想在重定向完成时向用户显示一条消息（例如更改生成的重定向...）。在页面输出后，改变头部变量导致PHP出错，我知道这一点。我的问题是，我应该如何做到这一点？

我现在的代码类似于

  // ...执行代码
 echo'更改成功。现在重定向...'; 
 header（'Location：index.php'）; 
  

，这是行不通的。我也看到了一个答案，建议我在开始和结束时使用 ob_start（）和 ob_flush（）我的页面，分别。但是这也没有解决我的问题，我仍然得到错误。

NB我只需要使用PHP，我不希望JavaScript用于重定向。

编辑：我最终使用JavaScript重定向，因为我需要在重定向之前向用户输出一些有用的消息，而PHP本身并不是最好的解决方案。

  header（refresh： 1; url = test.php）; 
 echo'This is a test'; 
 exit; 
  

I am trying to redirect a page after successful execution. However, I want to display a message to the user (e.g. 'Changed made. Redirecting...') while the redirection is done. Changing header variables after output in the page causes errors in PHP and I know this. My question is, how should I do this?

My current code is something like

// ... execution code
echo 'Changes made successfully. Now redirecting...';
header('Location: index.php');

and this doesn't work. I have also seen an answer on SO suggesting I use ob_start() and ob_flush() at the start and end of my page, respectively. But that didn't solve my problem either, I still get the error.

NB I need to use PHP only, I don't want JavaScript for redirection.

Edit: I ended up using JavaScript for redirection, as I needed to output some useful message to the user before redirecting, and PHP alone isn't the best solution for that.

解决方案

Echo after setting the header.

header("refresh:1;url=test.php); 
echo 'this is a test';
exit;
