如何在php数据库中插入csv文件的第一行？

$file = fopen('file.csv', 'r');
$firstRow = fgetcsv($file);
fclose($file);

$servername = "数据库服务器地址";
$username = "用户名";
$password = "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);
}

$tableName = "表名";
$insertColumns = implode(", ", $firstRow);
$insertValues = implode(", ", array_fill(0, count($firstRow), "?"));
$sql = "INSERT INTO $tableName ($insertColumns) VALUES ($insertValues)";

$stmt = $conn->prepare($sql);
$stmt->bind_param(str_repeat("s", count($firstRow)), ...$firstRow);
$stmt->execute();
$stmt->close();

$file = fopen('file.csv', 'r');
$firstRow = fgetcsv($file);
fclose($file);

$servername = "数据库服务器地址";
$username = "用户名";
$password = "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);
}

$tableName = "表名";
$insertColumns = implode(", ", $firstRow);
$insertValues = implode(", ", array_fill(0, count($firstRow), "?"));
$sql = "INSERT INTO $tableName ($insertColumns) VALUES ($insertValues)";

$stmt = $conn->prepare($sql);
$stmt->bind_param(str_repeat("s", count($firstRow)), ...$firstRow);
$stmt->execute();
$stmt->close();

$conn->close();
