如何使用htacess文件（mod_rewrite）模拟目录？

Question

what I try to do is to simulate directories with the help of a htaccess file. I have a website with a file like this:

http://www.domain.com/filename.php?t=yeah-a-title-2014

Now, I would like to rewrite the URL above to the following:

http://www.domain.com/directory1/yeah-a-title-2014/

If a visitor enters one of the two URLs, he should see the second one in his address bar but the content of the filename.php?t=yeah-a-title-2014 should be displayed.

I have no idea how to realize this. Any ideas?

This is better known as SEO-urls (search engine optimized), SEF-urls (search engine friendly), fancy urls and a couple more of those terms. The basic problem with these kind of constructions, is that they cause an infinite loop if not implemented correctly, and therefore usually the THE_REQUEST trick is used, because %{THE_REQUEST} is always equal to the request, even if the url is rewritten, which in turn prevents the external redirect from matching if the internal rewrite matches.

#External redirect
RewriteCond %{THE_REQUEST} ^(GET|POST)\ /filename\.php\?t=(.*)\ HTTP
RewriteRule ^ /directory1/%2/ [R,L]
#Change [R,L] to [R=301,L] after ALL rules do what you want them to do, and before your site goes live

#Internal rewrite
RewriteRule ^directory1/([^/]+)/?$ /filename.php?t=$1 [L]
