首先像这样更改您的连接：$host = 'localhost';

$db = 'nairobi';

$user = 'admin';

$pass = '123456';

$charset = 'utf8mb4'; // Always set charset for database

$port = '3308'; //Your port can be 3306 or 3307

$dsn = "mysql:host=$host;dbname=$db;port=$port;charset=$charset";

$options = [

PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,

PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC,

PDO::ATTR_EMULATE_PREPARES => false,

];

try {

$pdo = new PDO($dsn, $user, $pass, $options);

} catch (\PDOException $e) {

throw new \PDOException($e->getMessage(), (int)$e->getCode());

}

现在输入您的密码！您正在使用prepare语句，这会使您的代码足够安全。if (isset($_POST['submit'])) {

$first_name = $_POST['first_name'];

$last_name = $_POST['last_name'];

$email = $_POST['email'];

//You have a `TABLE` name call members so you dont need `TABLE` its causing problem

//Your query should look like this

$sql = 'INSERT INTO members (first_name, last_name, email) VALUES (:first_name, :last_name, :email)';

$stmt = $dbh->prepare($sql);

$stmt->execute([$first_name, $last_name, $email]);

//I removed array here which you dont need, you can directly add fields in execute.

$stmt->closeCursor();

//Use `closeCursor()` to free your connection instead unset or close.

}

最终确保您创建了一个数据库。确保您在数据库中创建了表调用成员。

如果您已完成所有操作，则您的代码将毫无问题地工作。
