ສ້າງລະບົບ PHP
ເລີ່ ມຕົ້ນດ້ວຍການສ້າງຕາຕະລາງຊີ່ member
CREATE TABLE `member` (
ÙserID` int(3) unsigned zerofill NOT NULL auto_increment,
Ùsername` varchar(20) NOT NULL,
`Password` varchar(20) NOT NULL,
`Name` varchar(100) NOT NULL,
`Status` enum('ADMIN','USER') NOT NULL default 'USER',
PRIMARY KEY (ÙserID`),
UNIQUE KEY Ùsername` (Ùsername`)
) ENGINE=MyISAM AUTO_INCREMENT=3 ;
--
-- Dumping data for table `member`

INSERT INTO `member` VALUES (001, 'win', 'win123', 'Weerachai Nukitram',
'USER');
INSERT INTO `member` VALUES (002, 'chai', 'chai123', 'Surachai Sirisart',

ກີ່ ຽວກັບຕາຕະລາງຈະປະກອບດ້ວຍ UserID , Username , Password , Name , Status ໂດຍຊີ່ ອງ
Status ເປັນໂຕບົງບອກວີ່ າເປັນ ADMIN ຫວີ່ າ User
