CI (C ODE I GNITER ) CodeIgniter is an Application Development Framework - a toolkit - for people who build web sites using PHP. Its goal is to enable you to develop projects much faster than you could if you were writing code from scratch, by providing a rich set of libraries for commonly needed tasks, as well as a simple interface and logical structure to access these libraries. CodeIgniter lets you creatively focus on your project by minimizing the amount of code needed for a given task.

C ODE I GNITER URL URL pada CI didesain lebih user friendly “URLs in CodeIgniter are designed to be search- engine and human friendly” CI menggunakan pendekatan url berbasis segment example.com/ news / article /my_article class method Id atau variabel yang akan dilewatkan melalui controller

URL S UFFIX Menambahkan url suffix example.com/index.php/products/view/shoes Menjadi example.com/index.php/products/view/shoes.html File yang harus dimodifikasi config/config.php Dengan url suffix, dapat menambahkan ekstensi sesuai dengan keiinginan.
