Blog-Demo-for-CSE-294 is a project mainly written in PHP, it's free.
This was built from scratch as a sample project for the ASU CSE 294 class
This project was meant to help you learn PHP and help you see the challenges that accompany even a small project like creating a blogging application. Hopefully you were able to learn a lot. Here is my sample code I created at the beginning of the semester. You may see that my code is very different from yours. For example, I have used objects, and you were not required to. If you have any questions, feel free to contact me.
