rest api，在php中规范化mysql返回的行数据

<?php
// 连接到MySQL数据库
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "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);
}

// 执行SQL查询
$sql = "SELECT * FROM your_table";
$result = $conn->query($sql);

// 规范化数据
$data = array();
if ($result->num_rows > 0) {
    while ($row = $result->fetch_assoc()) {
        $normalizedRow = array();
        foreach ($row as $key => $value) {
            $normalizedRow[$key] = $value;
        }
        array_push($data, $normalizedRow);
    }
}

// 关闭数据库连接
$conn->close();

// 返回规范化的数据
return $data;
?>
