I'm trying to remove .php from my URLs and add a trailing slash to the end. I've got the .php removal working just fine, but I'm struggling to get the trailing slash working.

Here's what I've got so far:

```
# Turn mod_rewrite on
RewriteEngine On
RewriteBase /

## hide .php extension snippet

# To externally redirect /dir/foo.php to /dir/foo
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s([^.]+)\.php [NC]
RewriteRule ^ %1 [R,L]

# To internally forward /dir/foo to /dir/foo.php
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^(.*?)/?$ $1.php [L]

```

Thanks in advance!
