Class plan.png What are we going to learn today?[edit]

  1. I am out sick today. Again. Blech.
  2. 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
