PHP 创建 MySQL 表

<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";
 
// 创建连接
$conn = mysqli_connect($servername, $username, $password, $dbname);
// 检测连接
if (!$conn) {
    die("连接失败: " . mysqli_connect_error());
}
 
// 使用 sql 创建数据表
$sql = "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
)";
 
if (mysqli_query($conn, $sql)) {
    echo "数据表 MyGuests 创建成功";
} else {
    echo "创建数据表错误: " . mysqli_error($conn);
}
 
mysqli_close($conn);
?>
