Code Downloads
Most of the code shown in this book can be found in a public repository on GitHub.Footnote 4 While the code of Chapter 3 (“A Self-Made ORM”) can be found on the “master” branch,Footnote 5 there is another branch available, called “doctrine,” Footnote 6 which holds the modifications made in Chapter 4 (“Hello, Doctrine 2!”). There is a third branch called “application” Footnote 7 holding the modifications made in the later chapters. As the demo application grows throughout the book, the application branch also includes a basic model-view-controller (MVC) framework, called Slim,Footnote 8 to better structure the application’s code, as well as Twitter’s Bootstrap Footnote 9 for some basic UI styling.
