htaccess redirect index.php to root (including subdomains)

Question

I'm trying to redirect index.php files to the root /, I've searched around and found several snippets of code similar to:

RewriteCond %{THE_REQUEST} ^.*/index.php 
RewriteRule ^(.*)index.php$ http://www.domain.com/$1 [R=301,L] 

This however won't work for subdomains, example below:

1. I have a subdomain: subdomain.domain.com
2. A user visits http://subdomain.domain.com/index.php
3. Using the htaccess above they are redirected to http://www.domain.com/ rather than http://subdomain.domain.com/

Does anyone know how to adjust the htaccess above so it will take into account the subdomain and redirect them to the appropriate location?

e.g. if a user visits http://subdomain.domain.com/index.php they will go to http://subdomain.domain.com/

Bonus Points:

Is there a htaccess that can just apply this rule to all folders?

So for any folder with an index.php they will just be redirected to it's root e.g. http://subdomain.domain.com/folder1/folder2/index.php would automatically go to http://subdomain.domain.com/folder1/folder2/

Answer 1

Do this:

RewriteCond %{THE_REQUEST} ^.*/index\.php 
RewriteRule ^(.*)index.php$ /$1 [R=301,L] 

Answer 2

I based the following code on @ThinkingMonkey's answer

RewriteRule ^(.*)index\.(php|html?)$ /$1 [R=301,NC,L]

It redirects URIs ending with index.php, index.htm or index.html to /. Works with subdirectories, too.

Also, notice the NC flag. It makes it case-insensitive. So it works even if the URI is in upper-case such as INDEX.PHP.

Answer 3

Can be use this

RewriteRule ^index\.php/(.*)$ http://www.example.com/$1 [R=301,L]
