redirecting with mod-rewrite

Question

The below rule I took from here and modified it (very little) so it adds a slash after removing the php file extension.

RewriteEngine on

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

So the url Domain.com/file.php will look like Domain.com/file/

And it works fine as long as I have a link or type in directly Domain.com/file/ but I want to keep all my links to my php files. So I want it to redirect someone to Domain.com/file/ if someone goes to Domain.com/file.php

But when I try to redirect (if I'm doing this properly)

RewriteEngine on

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.php -f
RewriteRule ^(.*)/$ $1.php [R=301,L]

But It doesn't redirect. :(

I'm not sure if I'm redirecting in correctly or if I'm simply not allowed to do this. Any advice is awesome.

I'm not entirely sure how it works with htaccess, but you could always just use php. Make this a file and include it at the top of all your pages:

<?php    
  $page = substr($_SERVER["SCRIPT_NAME"],strrpos($_SERVER["SCRIPT_NAME"],"/")+1);
  if(substr($page, -4)=='.php'){
    $pageURL = 'http';
    if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";}
      $pageURL .= "://";
    if ($_SERVER["SERVER_PORT"] != "80") {
      $pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"];
    } else {
      $pageURL .= $_SERVER["SERVER_NAME"];
    }
    header( "Location: $pageURL/" + substr($page, 0, -4)  );
  }
?>

EDIT: If you don't care about what the user sees in the address bar, just add an [R] (try taking away the =301,L part)
