User Guide (Static Page) Documentation Clarification Please

Thank (both of you) for your kind responses ... when I add it to the controller (Pages.php) then I get the following error when trying to view them

Code:

An uncaught Exception was encountered
Type: ParseError
Message: syntax error, unexpected 'public' (T_PUBLIC), expecting end of file

Filename: /Applications/MAMP/htdocs/CodeIgniter-3.1.5/application/controllers/Pages.php

Line Number: 9
Backtrace:

File: /Applications/MAMP/htdocs/CodeIgniter-3.1.5/index.php
Line: 315
Function: require_once

So, not sure why that would be the case, it is supposed to work ...
