PHP -- can someone help please!

The assignment is below, along with my code. I'm new to multidimensional arrays and am in need of someone to look over my code. Please update or just let me know what I'm doing wrong. THANKS!

Directions

-------------------

1.Home page

Welcome the user to the site with simple instructions of what they are supposed to do.

2. Lesson page

Inform the user about a topic of your choice. This can be a hobby of yours or related

to a new technique in web design/development.

3. Quiz page

Quiz the user on their knowledge of the content in your lesson page with at least five multiple-choice questions.

Technical Requirements:

1. Multi-file PHP template

Within your includes folder, you must have at least a header.html.php,

footer.html.php, and functions.php. Your pages will then include/require these pieces.

Be sure to use an external style sheet and put any images in a folder called images.

Your design will also be graded based on creativity and appeal.

2. The quiz

This part of the assignment will use arrays, loops and functions. Use one multidimensional

associative array to store the questions, choices and answers for this

quiz. Use a nested foreach loop to display the questions and choices. Create and use

a simple function to calculate the percentage based on the number correct out of the

total number of questions.

3. Validation and sticky forms

The form should be validated to ensure the user and answered all five questions

before calculating the score. After the user submits the page, it should always keep

the choices the user chose.
