Help me become a better developer!

Thanks for the replies, gents!

I'm slowly working on the sql injections holes - mainly just checking if ctype_digit() against ID values.

Code:

if( !$this->uri->segment(2) || !ctype_digit($this->uri->segment(2)) ) {

If that little number fails, it just defaults to pulling the newest post and showing related comments.

As far as $limit - I always know that's going to be a numerical value. It's only ever passed internally.

( get_latest_news(3) )
( get_latest_news(1) )

I'll give that SQL Binding thing a try.
