VIEWS Views are written in plain old PHP View scripts are placed in

application/views/scripts/ And further categorized

using the controller names Hence, we can create

Sub-directories index/ error/

Within these subdirectories you will find and create view scripts

that correspond to each controller action exposed Our default case

index/index.phtml error/error.phtml.
