Most effective way to code SEO friendly URLs?

Question

I currently use .htaccess and PHP to parse URLs in the following way:

URL:

http://blah.com/article/123_this-that-and-the-other


        

Answer 1

It is called "router".

See Zend Controller Router f.e.

Answer 2

You could get the whole query string as one paramter.

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

Then you can split the string with php and convert the different parameters into an array to do whatever you like with.
