Create SEF urls for our blog
===

We run a blog, and really need to tidy up the URL's using htaccess, but I am really stumped.

Example:

Working on a site, and I need to generate search engine friendlt URL's

So I have the url currently as: 

http://mywebsite.com/blog/read.php?art_id=11

Title of this page is:

**Why do Australians pay so much for Cars ?**

I need to change it to its corresponding SEF url. like so: 

http://mywebsite.com/blog/Why-do-Australians-pay-so-much-for-Cars-?

The question mark is part of the title, and we could remove these if its a issue. Any suggestions please ?

Also would prefer to drop the read.php portion. Need to create a rule that works across our entire blog.

They all follow the same pattern, only the art_id number changes
