Now that you’ve reached the end of your journey into learning the hows, whys, and wherefores of dynamic web programming, I want to leave you with a real example that you can sink your teeth into. In fact, it’s 10 examples, because I’ve put together a simple social networking project comprising all the main features you’d expect from such a site.
Across the various files, there are examples of MySQL table creation and database access, file inclusion, session control, DOM access, Ajax calls, event and error handling, file uploading, image manipulation, and a whole lot more.
Each example file is complete and self-contained, yet works with all the others to build a fully working social networking site. I have deliberately left styling and design to an absolute minimum to keep the examples short and easy to follow. This means that, as it stands, the end product is particularly usable on mobile platforms such as the iPhone, where reducing the file size and dimensions of web documents is important.
I leave it up to you to take any pieces of code you think you can use and expand on them for your own purposes. Perhaps you may even wish to build on these files to create a social networking site of your own.
