What are we going to learn today?[edit]

I am out sick today. Again. Blech.
Follow these instructions
1. Watch this video and ensure your PHPStorm connection settings are correct. Pay attention to detail. https://youtu.be/mm1pnvjgxgU
2. Make sure you have this form http://85.90.244.131/bm/bootstrap_template.html
3. Make sure you have an output page for your output, like this one: http://85.90.244.131/bm/exercise.php
4. watch this video to see a overview of our objective: https://youtu.be/uBF64QtdkG0
5. This video is where you will actually start working https://youtu.be/bFwwyiirg4c
6. This video is where you create the file to process your login form: https://youtu.be/yWuhNOxs4wM
7. This video actually processes the login form https://youtu.be/25eKEXUFY74
8. We now need a way of "remembering" if our user is logged in or not. we do this with sessions. Simple: https://youtu.be/_zkgXfq_6SU
9. Before we continue, the MOST SIMPLE program you will ever write: how to logout in PHP: https://youtu.be/7d9XIaxrjNg
10. The final step (for now) in our login cycle: https://youtu.be/OB_yiI4CegA

PLEASE read the next section about assessment!!!!!!!

What is our homework?[edit]

None.

How am I being assessed today?[edit]

You must create a working login system using bootstrap template you worked on in your last class.
The file below is ABOUT what your final file should look like. If you do not follow instructions you will be confused :-)
