使用PHP创建MySQL数据库和表格
示例代码demo：
```php
<?php
// 连接MySQL服务器
$servername = "localhost";
$username = "root";
$password = "password";
$dbname = "mydatabase";
$conn = new mysqli($servername, $username, $password, $dbname);
// 检查连接是否成功
if ($conn->connect_error) {
die("连接失败: " . $conn->connect_error);
}
// 创建表格
$sql = "CREATE TABLE mytable (
id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
firstname VARCHAR(30) NOT NULL,
lastname VARCHAR(30) NOT NULL,
email VARCHAR(50),
reg_date TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
)";
if ($conn->query($sql) === TRUE) {
echo "表格创建成功";
} else {
echo "Error creating table: " . $conn->error;
}
// 关闭连接
$conn->close();
?>
```
