PHP owes its appeal and popularity to its low barriers to entry. Anyone with access to a basic LAMP stack can get started in just a few hours, but if you want to write a production-level application, you need the right tools.

Git, though not specific to PHP, is critical to developing a maintainable project. This talk will guide you through these topics so that you have a basic understanding of the modern PHP developer's toolbox.
