如何获取RewriteRule来重定向现有和不存在的页面？

Question

Goal: Send all requests, regardless whether the directory/file exists or not, to http://example.com/index.php

What I have tried:

Rewrite Engine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ http://example.com/index.php [L]

It redirects URL's of non-existing directories/files fine, but when I access an existing subdirectory and file http://example.com/test/test.php it only gives me the contents of the test.php page instead of the main index.php page.

If I understand correctly, the RewriteCond %{REQUEST_FILENAME} !-f and RewriteCond %{REQUEST_FILENAME} !-d tell it to perform the RewriteRule if those criterias are met, which makes sense why it only redirects on non-existing directories and files. But I've tried removing those RewriteCond 's, and all it does is put my site into a redirect loop.

I've also tried doing

Rewrite Engine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} -f
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^(.*)$ http://example.com/index.php [L]

But then it doesn't redirect at all.

What do I have to put to accomplish this?

Answer 1

Your first example would only redirect things that does not exist to your index.php as the conditions you have there:

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

Basically means if file or directory does not exist, do this.

Your second example is even worst as it tries to see if a file, directory exist and does not exist which makes no sense.

To redirect anything existent or not to a main handler in this case index.php all you need is the below:

Options +FollowSymLinks -MultiViews

RewriteEngine On
RewriteBase /

RewriteCond %{REQUEST_URI} !^/index.php$ [NC]
RewriteRule ^ index.php [L]

The condition makes sure you're not redirecting it to yourself to prevent a loop. If you're running HTTPD version 2.4 and above you can simple use:

Options +FollowSymLinks -MultiViews

RewriteEngine On
RewriteBase /

RewriteRule ^ index.php [END]

The flag [END] takes care of not executing any further redirects.

Answer 2

If you want to redirect any url, just use a RewriteRule , so it will redirect any non/existent file/directory to the RewriteRule rule

RewriteEngine on
RewriteBase /

RewriteCond %{ENV:REDIRECT_STATUS} 200
RewriteRule ^ - [L]

RewriteRule ^(.*)$ index.php [L]
