header('HTTP/1.0 404 Not Found'); not doing anything

Question

I have a 404.php file in my site\'s main directory and I was using header(\'Location: 404.php\'); for a while until someone said that you should use heade

Answer 1

No, it probably is actually working. It's just not readily visible. Instead of just using the header call, try doing that, then including 404.php, and then calling die.

You can test the fact that the HTTP/1.0 404 Not Found works by creating a PHP file named, say, test.php with this content:

<?php

header("HTTP/1.0 404 Not Found");
echo "PHP continues.\n";
die();
echo "Not after a die, however.\n";

Then viewing the result with curl -D /dev/stdout reveals:

HTTP/1.0 404 Not Found
Date: Mon, 04 Apr 2011 03:39:06 GMT
Server: Apache
X-Powered-By: PHP/5.3.2
Content-Length: 14
Connection: close
Content-Type: text/html

PHP continues.
