I was able to attend Civi-CRM training whilst in London. The guys from Civi-CRM walked us through the database structure, main code base folder/file structure...
Recently Nick Hodge (Open Source Evangelist) from Microsoft asked me if I would like to do an introduction for the new School of PHP that Microsoft was launching. The School of PHP is a very cool idea and I could not say no to something that could get more people into PHP development.
The school is an online course which has video tutorials that help walk people through writing web applications with PHP using Microsoft Technologies.
There are some great introduction tutorials as well as more advanced ones, so there should be something there for those curious about PHP and also the seasoned developer.
