A view is simply a web page, or a page fragment, like a header, footer, sidebar, etc. In fact, views can flexibly be embedded within other views (within other views, etc., etc.) if you need this type of hierarchy. Views are never called directly, they must be loaded by a controller. Remember that in an MVC framework, the Controller acts as the traffic cop, so it is responsible for fetching a particular view.

URI Segments The segments in the URL, in following with the Model-View-Controller approach, usually represent: example.com/class/function/ID The first segmen

CodeIgniter’s database abstraction allows you to use transactions with databases that support transaction-safe table types. In MySQL, you’ll need to be running InnoDB or BDB table types rather than the more common MyISAM. Most other database platforms support transactions natively. If you are not familiar with transactions we recommend you find a good online resource to learn about them for your particular database. The information below assumes you have a basic understanding of transactions. C
