What you are talking about is called as slug.

So, how to use slug?

Will explain with an example:
URL - http://www.example.com/products/apple-iphone-5S-16GB-brand-new/

1) Assuming you are having a product page and ofcourse product page needs some data from URL to understand which product to display.
2) Before we were querying our database using the id we are getting from the URL. But now we'll do the same thing (querying our database) just replacing id with slug and thats it!
3) Hence adding an additional column in your database named slug. Below will be your updated product database structure (just an example).

Columns                       Values

id (int(11), PK)              1
title (varchar(1000))         Apple iPhone 5S 16GB
slug (varchar(1000))          apple-iphone-5S-16GB-brand-new
price (varchar(15))           48000
thumbnail (varchar(255))      apple-iphone-5S-16GB-brand-new.jpg
description (text)            blah blah
...
...


I've also answered on slug before. Check if it helps.

  • What I gave is just an example to explain. You have to run your mind to match it up according to your requirement. – Parag Tyagi Dec 06 '14 at 13:27

This has to be done using the routes class. 

   $route['product/(:num)'] = "catalog/product_lookup_by_id/$1";

I would suggest you look at the user guide for more info.
