CS 315 Homework 3: PHP
Assigned: 14 February 2020 Due: 24 February 2020
This homework problem is to be done individually, not in pairs or
other groups. Your completed assignment should be submitted using
the Assignment Submission Page. You
should submit (in one submission) both the URL of the actual PHP that
runs and the URL of a .phps file with your source, so you might submit
the URL of a page that has both of those URLs on it.
Write a program using a single PHP file that gives the user a five
question quiz concerning whatever topic you choose. Initially your
PHP program should present the user with a form containing the five
questions and giving them the ability to indicate their answers. Once
the user has answered at least one question on the quiz and submitted
their responses, your PHP program should grade their answers and tell
them the result, including which questions they got right and which
they got wrong and a summary of their score. Specific requirements:
- Radio buttons are the most obvious way to ask for input for
multiple-choice questions, but other possibilities can also be used,
such as menus. Up to 3 of your questions can be of this form, where
all of the possible answers are presented to the user and they choose
one.
- At least 2 of your questions must be of a more open-ended form,
where the user types text. When you grade these questions, you should
allow a reasonable range of possible responses to be counted as
correct. You will need to use regular expressions to match correct
responses. Exactly what counts as a correct answer is up to you, but
you should try to be flexible. For example, if the question is "What
is the best public liberal arts and sciences university in the Midwest?",
reasonable answers include Truman State University, Truman State, TSU,
Northeast Missouri State University, etc. . ., but unreasonable answers
should not be allowed (e.g., Northwest Missouri State University or
Northern Iowa University).
- Document your code well, so that it is obvious to me what kind of
right answers you are trying to accept and what kind of wrong answers
you are attempting to reject. If you aren't clear about this, I will
make my own assumptions and grade you down if you don't live up to
them.
- All of your code should be contained in one .php file. Of course,
be sure to have a .phps file as well. Recall that you can create a .phps
file (once) by typing:
ln -s hw3.php hw3.phps
for example.
