mod_rewrite/htaccess redirect issue! (recursion limit)

Question

I'm trying to create my mod_rewrite file so that basically all of the .php extensions are removed when you view a file.

Here's my .htaccess:

RewriteEngine On
DirectoryIndex index.php
ErrorDocument 404 /errors/404.php
ErrorDocument 403 /errors/403.php
ErrorDocument 500 /errors/500.php
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule (.*) $1.php [L]

Now here's the error i get from my apache log when trying a random name:

[Tue Jan 31 17:26:05 2012] [error] [client 127.0.0.1] Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace.

How do i go about fixing it? Thanks

Where is the recursion? I'm pretty bad at .htaccess writing so this was generated and partly written! — user1180934

Well i simply want to remove the .php to all files i have so for example about.php, index.php etc. And then I obviously have the ErrorDocuments relating to each error! The test for "aboutasdfoi" was just a test as aboutasdfoi.php doesn't exist, so I was hoping it would go to my 404 page! — user1180934

EDIT: NOT SOLVED! Ok I solved the error myself, just found out it's the ( and ) causing it, which i assume is the recursion :) I'll look into it more now! — user1180934

To hide .php extension use this code:

# To externally redirect /dir/foo.php to /dir/foo
RewriteCond %{THE_REQUEST} ^GET\s.+\.php [NC]
RewriteRule ^(.+)\.php$ /$1 [R=301,L,NC]

# To internally redirect /dir/foo to /dir/foo.php
RewriteCond %{REQUEST_URI} !\.php$ [NC]
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule . %{REQUEST_URI}.php [L]

You're welcome. If it works for you then can you accept this answer to close this Q&A.

anubhava, have you tried a test vector fred?param=1. Your algo will generate fred?param=1.php.php.php.php etc. before barfing on a recursion limit. %{REQUEST_URI} includes any get parameters.

@TerryE wrote: %{REQUEST_URI} includes any get parameters. Sorry for being blunt but you are absolutely wrong. Pls read some Apache docs on mod_rewrite before making comments like this. Just fyi: %{REQUEST_URI} contains only the URI and %{QUERY_STRING} actually has all the Get parameters.

:Oops: Got to +1 you on that. My confusion is that the Environment variable REQUEST_URI does, but the rewrite variable %{REQUEST_URI} doesn't as you can see here. This is just a phpinfo() but I've added a diagnostic RewriteRule .? - [E=REQ_URI:%{REQUEST_URI}] to my docroot .htaccess file. Search for "REQUEST_URI" and "REDIRECT_REQ_URI".
