PHP: Unable to change 404 status code, but no error in header ()

I am rendering uncharted pages in my PHP custom website. For this, I created a .htaccess file with this single line:

ErrorDocument 404 /index.php

At the beginning of index.php I placed this code:

header($_SERVER['SERVER_PROTOCOL'].' 200 OK', true, 200);

This works great in my WAMP environment. I check the http headers and it throws:

Status=OK - 200

But on my Linux hosting I always get:

Status=Not Found - 404

And the weird part is that PHP doesn't throw any errors at all ... it overrides my headers somehow.

I need to change the title of the status code, otherwise IE7 and IE8 won't process my result page. Other browsers can handle this.

Maybe I need something in .htaccess or php.ini but nothing was found. Or if you know of any other method to redirect 404 and return 200, please let me know.

The best way to overwrite non-existent pages in a PHP file is as follows:

RewriteEngine On
RewriteCond %{SCRIPT_FILENAME} !-d
RewriteCond %{SCRIPT_FILENAME} !-f
RewriteRule (.*) index.php


This is where mod_rewrite is used to change anything that is not a directory and not a file in your PHP script. Just remember that if your PHP script receives a request for something that isn't there, it should send a 404 header.

Fast-cgi can be enabled depending on your web server configuration. Then you need an alternative syntax (as stated in the PHP documentation):



header("Status: 200 OK"); // for fast cgi
header($_SERVER['SERVER_PROTOCOL'] . " 200 OK");
