Folders-like URL with PHP?

Question

Hi,

ever since I added this htaccess to my website, I noticed a HUGE slowdown, and my error logs are filled with errors such as

PHP Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource in page.php on line 79

I've got up to four of these per second. Most of the time it works though.

The htaccess consisted of two similar rules: one with two GET vars, another one with only one. Maybe they interfere with each other?

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)\/(.*)$  index.php?var1=$1&var2=$2 [L]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$  page2.php?var1=$1 [L]

Anyway, I just rewrote a PHP script that handles of all the strings and redirects where it should, and my website is now fast again. But is there a way to hide mypage.php?var1=la&var2=lu and still have URLs that look like folders?

Thanks for your replies!
