I read this tutorial, and recognised the structure as being similar to Ruby on Rails. I had previously given up on RonR as I did not want to learn a new language.
I have installed CakePHP and found a problem. CakePHP 1.3.4 is the current version; it does not support SQLite3 !!
Having set the database configuration file, and calling up the initial page in my browser, CakePHP creates the database file (empty), and says it can access the database. When you create a table it and refresh the browser, it now says it cannot access the database. I eventually found the problem when using the Bake utility that gave me a decent error message. I am not going back to SQLite2, so it's over to MySQL for me.
