How to create these webpages

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>
....
....

And then,

# 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.
