Background

The PHP development environment that I have devised was created by taking a set of sample programs which I had assembled for a previous language and rewriting them in PHP. These sample programs were used as patterns or templates for all other programs in my applications as they represented all the combinations of structure and behaviour that I had encountered. To build a new component all I had to do was identify the right template, then specify which database tables(s) and columns I wished to show on the screen for the new component.
