hide extension .php in url mod_rewrite - php

Question

I have a website in PHP, and I'm trying to hide the extension. I've found a couple of things via Google, but they all seem to be too complicated, or they redirect index to index.php: like if you write name.com/contact it goes to name.com/contact.php. I don't want that, I just want:
www.name.com/es/index.php to be www.name.com/es/inicio
www.name.com/es/empresa.php to be www.name.com/es/empresa
www.name.com/es/productos.php to be www.name.com/es/productos
www.name.com/es/clientes.php to be www.name.com/es/clientes
www.name.com/es/recetas.php to be www.name.com/es/recetas
www.name.com/es/contacto.php to be www.name.com/es/contacto
www.name.com/en/index.php to be www.name.com/en/home
www.name.com/en/company.php to be www.name.com/en/company
www.name.com/en/products.php to be www.name.com/en/products
www.name.com/en/clients.php to be www.name.com/en/clients
www.name.com/en/recepis.php to be www.name.com/en/recepis
www.name.com/en/contact.php to be www.name.com/en/contact
the /en/ folder is English version and the /es/ folder is the Spanish version
Also the links inside the website, would be also without the extension.
E.g, an image linked to clientes would be clientes and not clientes.php and if somebody tries to go to /page.php, it still works but it redirects to /page.

Answer 1

The htacces file should look like this:
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.php -f
RewriteRule ^(.*)$ $1.php
You redirect any php file in the url with the same name withouth the "php".
Then in your php files, you can check to see if the url contains the extension (http://blabla.com/bla.php) and redirect the page to the same one withouth the extension.
So, at the beginning of each php file you should call this function :
function redirectIfNeeded(){
$url = $_SERVER["REQUEST_URI"];
if(preg_match("/\.php/$", $url))
header("Location: ".preg_replace("/\.php/",$url));
}
