Hi all.I am not sure I am posting in correct forum or not, but experts over here might help me

Hi have got a code of codeigniter site, and I need to convert it in wordpress.This seems to be a complicated precess for me as I dont have slightest idea about codeigniter.

I would like to know how does the navigation works so that I could open the file and use it for reference.

Like, menu item Buy shows link:http://www.yoursite.com/landing/803,
lease:http://www.yoursite.com/landing/806
and Our Results:http://www.yoursite.com/listings/our

Can anyone tell me what does this mean?
