連接數據庫
$db = new MySQLi(‘localhost‘,‘root‘,‘root‘,‘z_1031‘);
!mysqli_connect_error() or die(‘連接失敗‘);
$db->query(‘set names utf8‘);
return $db;

創建數據庫
$sql = "CREATE DATABASE myDB";
if ($conn->query($sql) === TRUE) {
echo "數據庫創建成功";
} else {
echo "Error creating database: " . $conn->error;
}


創建 MySQL 表
使用use myDB 來選擇要操作的數據庫：
use myDB;
創建"MyGuests" 的表,5個列： "id", "firstname", "lastname", "email" 和 "reg_date":
CREATE TABLE MyGuests (
id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
firstname VARCHAR(30) NOT NULL,
lastname VARCHAR(30) NOT NULL,
email VARCHAR(50),
reg_date TIMESTAMP
)
