Basically, and simple if you were to rewrite
www.site.com/news.php?id=123
to
www.site.com/this_is_news_title
You should create a file called .htaccess
and put it inside your htdocs folder and write in it the following
Options +FollowSymLinks -MultiViews
# Turn mod_rewrite on
RewriteEngine On
RewriteBase /
RewriteRule ^news/([0-9]+)/.*$ /news.php?id=$1 [QSA,L,NC]
Try it and play around with it.
