you'll need share info urls in question, however, here illustration http://zenverse.net/seo-friendly-urls-with-htaccess/. rewrite rule go in .htaccess file.

rewriterule ^topic/([a-za-z0-9]+)/$ index.php?topic=$1

so url index.php/topic=something.

the ([a-za-z0-9]+) correlates $1. regex look letters , numbers. means topic/something map index.php?topic=something.

in case $1 category names/ids.
