如何在php中将变量数组单独插入数据库？

$servername = "数据库服务器地址";
$username = "数据库用户名";
$password = "数据库密码";
$dbname = "数据库名";

$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
    die("连接数据库失败: " . $conn->connect_error);
}

$myArray = array("John", "Doe", "john.doe@example.com");

$stmt = $conn->prepare("INSERT INTO your_table_name (column1, column2, column3) VALUES (?, ?, ?)");
$stmt->bind_param("sss", $myArray[0], $myArray[1], $myArray[2]);

if ($stmt->execute()) {
    echo "数据插入成功";
} else {
    echo "数据插入失败: " . $stmt->error;
}

$stmt->close();
$conn->close();

$servername = "数据库服务器地址";
$username = "数据库用户名";
$password = "数据库密码";
$dbname = "数据库名";

try {
    $conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    
    $myArray = array("John", "Doe", "john.doe@example.com");

    $stmt = $conn->prepare("INSERT INTO your_table_name (column1, column2, column3) VALUES (?, ?, ?)");
    $stmt->execute($myArray);

    echo "数据插入成功";
} catch(PDOException $e) {
    echo "数据插入失败: " . $e->getMessage();
}

$conn = null;
