.htaccess mod_rewrite subdirectory to URL parameter

Question

I hope this was not asked over and over again before, but I didn\'t get further to an answer using google, w3schools and so on. So here is my question: I\'m writing a script

Answer 1

Thanks for all the help so far! You guys are just awesome!

I figured out that a symbiosis of both of your solutions works well for me:

RewriteEngine on
RewriteBase /projects
RewriteCond %{SCRIPT_FILENAME} !-f
RewriteCond %{SCRIPT_FILENAME} -d
RewriteRule ^([^/]+)/?$ index.php?dir=$1 [QSA,L]

Of course only without [R], this was my fault. (See my question edit for another question please).
