URL Rewrite not working or rewriting urls
===

I've been trying to write a htaccess rule to rewrite my urls for the past 48 hours with no luck, ive even tried using a generator and none of the help Ive received on here seems to have helped neither so ill explain as detailed as I can.

Om running PHP on an APACHE server, mod-rewrite is enabled and my website directory where I have been placing my .htaccess file looks like this...

On Index.php there are a number of users listed, each one has a view more button that when clicked takes you through to user-profile.php, the link that does that looks like this...

    http://mysite.com/user-profile.php?userID=1&firstName=Liam&lastName=Gallagher

I now want to rewrite my urls so the link actually looks like...

    http://mysite.com/missing-people/1/Liam/Gallagher

Any helps greatly appreciated!
