如何将复选框中的多个值添加到mysql数据库

<?php
// 获取前端提交的复选框值
$checkboxValues = $_POST['checkbox'];

// 连接到MySQL数据库
$servername = "localhost";
$username = "your_username";
$password = "your_password";
$dbname = "your_database";

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

// 准备插入数据的SQL语句
$sql = "INSERT INTO your_table (checkbox_value) VALUES (?)";

// 使用预处理语句
$stmt = $conn->prepare($sql);
$stmt->bind_param("s", $checkboxValue);

// 逐个插入复选框值
foreach ($checkboxValues as $checkboxValue) {
    $stmt->execute();
}

// 关闭数据库连接
$stmt->close();
$conn->close();
?>
