For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
Accounts in PHP - an OO demo

I've written a new demonstration in PHP ...

* a base class of line items for your accounts
* subclasses for bills and invoices you issue
* a sample application that takes a number of bill and invoice items and produces an accounts table and total

All in the ONE course file as a demo ... here.

For a "live" application, the classes would probable be held in a separate file so that they could be shared across between a whole lot of different pages, and of course they would use a lot more attributes and be populated from files or databases

The example will work equally well in PHP5 and PHP4, even though you'll have been told that the OO model has changed between the two version!
