PHP code for a simple shopping cart

While researching about web site shopping cart, I was curious how difficult building a shopping cart would be. I would like to try to see if I could implement this one my Interactive Tutorial website but gozips doesn't allow php code to be implemented. I came across this site that gives a very easy tutorial on how to make a php shopping cart.

The shopping cart uses the server-side language PHP and a MySQL database. Some of the code can be confusing to understand but if you look at it carefully it can be under stood. I have never coded in PHP before but I can kind of understand this segment of code setting up the database

  1. CREATE TABLE books (
  2. id int(6) unsigned NOT NULL auto_increment,
  3. title varchar(100) NOT NULL default '',
  4. author varchar(100) NOT NULL default '',
  5. price decimal(3,2) NOT NULL default '0.00',
  6. PRIMARY KEY (id)
  7. ) TYPE=MyISAM;
The id will be an integer with the maximum of 1 million books. I think the varchar(100) give the title and the author a 100 character maximum. The price decimal(3,2) makes the price a decimal with 2 decimal places and the maximum be $999.

This shopping cart will also give you a running total of the price and of how many items are in the shopping cart. It show you how to remove, update and add more items to your shopping cart.
