hide extension .php in url mod_rewrite

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 in

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));
}
