Since it’s just a project. I won’t go too much into detail but would give you a simple idea:
You can do something like this:
# Home.php <a href="https://stackoverflow.com/questions/53984189/checkOutReviews.php?subject=1">Subject One</a> <a href="checkOutReviews.php?subject=2">Subject Two</a> .... ....
# checkOutReviews.php $subject_id = $_GET['subject']; /** Get subject details from the database or any other storage of your choice **/ /** and just display them **/
This way you won’t have to create pages for each of your subjects.
