to lazy to elaborate
I'll do it anyway!
The tutorial code is written with PHP classes, objects and heredoc syntax , which IMO is not suitable for a beginner audience.
The CMS created in the tutorial apparently lets you edit pages' raw HTML code from a form. For a CMS user that doesn't know HTML that's not too useful, while those that do know HTML might as well edit inclusion text files in a text editor and upload with an FTP program. (A CMS like this might be useful if you know HTML but is away from your own computer, though.)
Finally the tutorial doesn't show how to protect the CMS from unauthorized use, and indeed it seems the demo version has been removed due to readers posting malicious javascript in it.
