mod_rewrite：带有两个 GET 变量的 URL 尾部斜杠

Question

I'm in the process of overhauling one of my projects, a web based booking system, but I'm having a bit of an issue with my htaccess file. The old system was pretty standard, with .php scripts in the route of the website, I had a rule hiding my extensions, and I resultantly had a URL like /viewinvoce?ID=1. I've been trying to find out how to rewrite this URL so it looks a lot neater - in the format /viewinvoice/1, and I'm getting there, but I have a slight problem...

The URL /test works - it adds a trailing slash making the URL /test/, and the value 'test' is passed to the webpage.

The URL /test/ works as above, a trailing slash isn't added since it already exists, and 'test' is passed to the webpage.

The URL /test/1 also works, 'test' and '1' are both passed to the web page,

but when a slash is type after 1 (/test/1/) the page throws a 404.

My .htaccess file

RewriteEngine On
RewriteRule ^([^/]*)/([^/]*)$ /index.php?PID=$1&ID=$2 [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*[^/])/(.*[^/])$ http://%{HTTP_HOST}/$1$2/ [L,R=301]

My simple PHP script..

<?php
    echo $_GET['PID'];
    echo '<br>';
    echo $_GET['ID'];

Ideally, I'd like the .htaccess file to add a second trailing slash to the second variable passed, but I'm a bit confused at this point, and ideally a second pair of eyes would be useful!

Try these rules:

RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule !/$ %{REQUEST_URI}/ [L,R=301]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]

RewriteRule ^([^/]+)/([^/]+)/?$ index.php?PID=$1&ID=$2 [L,QSA]

RewriteRule ^([^/]+)/?$ index.php?PID=$1 [L,QSA]
