What Are They? Add basic functionality Similar to Javascript libraries, but not merely a bunch of nifty objects and functions Provide an architecture in which to create your project Necessarily extensible

Add basic functionality

Similar to Javascript libraries, but not merely a bunch of nifty objects and functions

Provide an architecture in which to create your project

Necessarily extensible

Who Cares? (Pros) Promotes code reuse Speed up the coding process by reducing the amount of “ overhead ” code to write, such as: Database access Authentication and session management Data validation and sanitation URL mapping and management Security Code is easier to maintain within an architecture

Promotes code reuse

Speed up the coding process by reducing the amount of “ overhead ” code to write, such as:

Database access

Authentication and session management

Data validation and sanitation

URL mapping and management

Security

Code is easier to maintain within an architecture

Cons Fairly steep learning curve Confined to the framework's chosen architecture and idiosyncrasies Slower than pure PHP Too many to choose from

Fairly steep learning curve

Confined to the framework's chosen architecture and idiosyncrasies

MVC Architectural pattern, separates code by function/purpose. - Model - Representation of Information/Data - Controller - (Business) Logic - View - Output, HTML, javascript..

CodeIgniter Not strictly MVC No assumptions made, no "magic" Simple syntax Can use straight PHP code in most places Everything is based off a "core object" ex. $this->load->model('model_name') $this knows everything about the application, can be used anywhere to access any setting Easily extendable Large community of 3rd party plugins Great documentation/community

CodeIgniter Database Access Can use regular SQL syntax CI uses a modified version of the Active Record Database Pattern Active Record Database Pattern (in CI) Allows simplified DB access with minimal scripting Database independent (query syntax is generated by the DB adapter) Queries automatically escaped $this->db->get('my_table'); "SELECT * FROM my_table";
