Seeking php help -

I'm trying to put together a multiple choice quiz and could use some help. I'm not entirely sure how I would keep score and return the percentage, this should be a function. I'm also not sure how to apply my multiple choice quiz into my page. I've pasted the instructions, and my code so far - thanks for your time and help!

Intructions

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.

Validation and sticky forms

The form should be validated to ensure the user and answered all five questions before calculating the score.
