如何在php中将所选数据从flutter排序到mysql

<?php
// 接收来自Flutter的POST请求
$data = $_POST['selected_data'];

// 对所选数据进行排序
sort($data);

// 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);

// 检查连接是否成功
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

// 编写SQL查询语句
$sql = "INSERT INTO your_table (column_name) VALUES ";

// 构建插入数据的SQL语句
foreach ($data as $value) {
    $sql .= "('$value'),";
}

// 去除最后一个逗号
$sql = rtrim($sql, ",");

// 执行SQL查询语句
if ($conn->query($sql) === TRUE) {
    echo "数据插入成功";
} else {
    echo "数据插入失败: " . $conn->error;
}

// 关闭数据库连接
$conn->close();
?>
