Yep you will need knowledge of PHP and MySQL (or another other database, but if I create an example it will be with MySQL).
Before I start, the records i am using in the database are wrong, I don't know the date so i just made one up. And I am very tired, so if i make a mistake I will correct it next time I'm on. Also i will post links at the end of this thread.
You would create a database, called eg:
Database Name: film_website
Database Table: reviews
---------------------------------------------------------------------------
| id | film_name | film_genre | release_date |
---------------------------------------------------------------------------
| 1 | James Bond: Gold finger | Action | 1992 |
| 2 | The Sound Of Music | Music | 1987 |
| 3 | James Bond: Octopussy | Action | 1994 |
| 4 | Die Hard 2 | Action | 1998 |
---------------------------------------------------------------------------
Now you have records in your table, you can manipulate the data using PHP. Just skipping a big shunk of information here, but what you can do is this:
You can basically write a PHP/MySQL script that says:
SQL: SELECT * FROM reviews WHERE film_genre = "Action"
English: SELECT all of the data FROM reviews table WHERE film_genre = "Action"
This will select row, 1,3,4 from the database.
When you extract the data you can sort the data by any column in the database, eg the "film_genre" column, or the "release_date" column. You do this by adding to this SQL command:
SQL: SELECT * FROM reviews WHERE film_genre = "Action" ORDER BY release_date DESC

You will also need to familiarize yourself with PHP (http://www.php.net/)
Let me know how your finding this, its the first tutorials based post i have ever written, so I don't know how understandable your going to find it.
