为什么不是在Apache显示404错误，当我发送404头用PHP？ [英] Why doesn't apache show a 404 error when I send a 404 header with php?

问题描述

我有一个标题（'HTTP / 1.0 404未找​​到'）; 某处沿code，但它不重定向到Apache默认的404页出于某种原因。

I have a header('HTTP/1.0 404 Not Found'); somewhere along the code but it doesn't redirect to the Apache's default 404 page for some reason.

我对每一个请求到index.php重定向.htaccess文件重写规则。莫非是这个问题？

I have a Rewrite Rule on the .htaccess file that redirects every request to index.php. Could that be the problem?

推荐答案

标题是不是告诉Apache来显示它的404页。相反，在的阿帕奇显示其404页，它发送一个404头与它一起。头是为了有意义的的浏览器的，而不是服务器。阿帕奇显示404时，它无法找到正确的文件显示。既然你的PHP脚本是，阿帕奇已经发现它可以显示，因此不会显示它自己的404页的文件。

The header is not what tells Apache to display it's 404 page. Rather, when Apache displays its 404 page, it sends a 404 header along with it. The header is meant to have meaning to the browser, not the server. Apache displays a 404 when it can't find the proper file to display. Since you're in a PHP script, Apache has already found a file it can display, and thus won't show its own 404 page.
