在表中输出一些但不是全部php编码的JSON数据

<?php
// 连接到数据库并获取数据
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

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

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

// 将数据转换为JSON格式
$data = array();
if ($result->num_rows > 0) {
    while ($row = $result->fetch_assoc()) {
        $data[] = $row;
    }
}

// 切片数据，只输出部分数据
$slicedData = array_slice($data, 0, 10); // 输出前10条数据

// 输出JSON数据到表中
echo "<table>";
foreach ($slicedData as $item) {
    echo "<tr>";
    echo "<td>" . $item['column1'] . "</td>";
    echo "<td>" . $item['column2'] . "</td>";
    // 添加更多列...
    echo "</tr>";
}
echo "</table>";

$conn->close();
?>
