Removing .php extension for first directory only

[arandomdan]

I have my .htaccess file set up to omit .php extensions from URLs. For instance:

mysite.com/page
mysite.com/item
mysite.com/about

Read from:

mysite.com/page.php
mysite.com/item.php
mysite.com/about.php

Which is great; however, I use the remaining part of the URL for parameters, which I want to be ignored. For instance, I want:

mysite.com/item/1234567890/a-product

To read from:

mysite.com/item.php

Rather than:

mysite.com/item/1234567890/a-product.php

Any idea how I can accomplish this in .htaccess? Here is my current .htaccess file:

RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.php -f
RewriteRule ^(.*)$ $1.php

If you can have a .htaccess in each directory then create a .htaccess for the directories you don't want to omit the .php and turn RewriteEngine off.

RewriteEngine Off
