PHP标头("Location:/404.php"，true，404)不起作用 [英] PHP header( "Location: /404.php", true, 404 ) does not work

问题描述

我想使用以下内容将数据库中不再存在的页面重定向到自定义404页面:

I'd like to use the following to redirect pages that are no longer present in the database to the custom 404 page:

ob_start();
....
if ( !$found ):
  header( "Location: /404.php", true, 404 );
  exit();
endif;

但这实际上并不会重定向，而只会显示一个空白页面(由于在向浏览器输出任何内容之前调用exit().)

But this actually does not redirect, but just shows an empty page (because of the exit() call before any output to the browser).

我也尝试了以下方法:

if ( !$found ):
  header( "HTTP/1.1 404 Not Found" );
  exit();
endif;

.htaccess文件中带有'ErrorDocument 404/404.php'，但这也只显示一个空白页面.

With a 'ErrorDocument 404 /404.php' in my .htaccess file, but this also just shows an empty page.

如果我这样做:

if ( !$found ):
  header( "HTTP/1.1 404 Not Found" );
  header( "Location: /404.php" );
  exit();
endif;

它确实重定向，但带有302标头.

It does redirect, but with a 302 header.

任何帮助将不胜感激.

推荐答案

也许没有重定向?

if ( !$found ):
   include('../404.php');
   exit();
endif;
