Write a PHP QUIZ web application using two files, one for the HTML form elements and one
for the PHP processing of the form elements. The application should present a PHP quiz to the 
user consisting of five questions about PHP. Each question should have four possible answers and
should consist of radio buttons. The form should be attractive, usable and titled accurately. The
 feedback page should provide whether the answer was right or wrong, appropriate messages, a score
 and a website for further research if the answer was wrong (for each wrong answer a different
 website location).
 

Keep in the mind the program should use functions and be efficient. It should not be a large grouping
 of if statements.
