DATABASE:
— You’ll need to create a database (I named mine ‘records’ but it can be changed) using PHPMyAdmin
— Save the included sql file on your desktop as a .txt file
— Once you’ve created the database, make sure the database is selected, then click the “import” tab
— Select the .txt file on your desktop, and import it into your database. PHPMyAdmin will create all of the necessary tables/import some test data for you to play with

SQL file:

--
-- Table structure for table `players`
--

CREATE TABLE `players` (
 `id` int(11) NOT NULL auto_increment,
 `firstname` varchar(32) NOT NULL,
 `lastname` varchar(32) NOT NULL,
 PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=5 ;

--
-- Dumping data for table `players`
--

INSERT INTO `players` VALUES(1, 'Bob', 'Baker');
INSERT INTO `players` VALUES(2, 'Tim', 'Thomas');
INSERT INTO `players` VALUES(3, 'Rachel', 'Roberts');
INSERT INTO `players` VALUES(4, 'Sam', 'Smith');

Save these php files all in the same folder in a place where you can run them using your server (I’m assuming you are using something like WAMP for the server? I’m not sure if Dreamweaver includes something like that by default.)
