PHP和Vue：如何实现会员积分的使用历史查询

<?php
header('Content-Type: application/json; charset=utf-8');

$servername = "localhost";
$username = "root";
$password = "password";
$dbname = "your_database";

$conn = new mysqli($servername, $username, $password, $dbname);
$conn->set_charset("utf8");

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

<?php
// 获取指定会员的积分使用历史记录
if ($_SERVER['REQUEST_METHOD'] == 'GET' && isset($_GET['member_id'])) {
    $member_id = $_GET['member_id'];

    $sql = "SELECT * FROM member_points_history WHERE member_id = $member_id ORDER BY create_time DESC";
    $result = $conn->query($sql);

    if ($result->num_rows > 0) {
        $rows = array();
        while ($row = $result->fetch_assoc()) {
            $rows[] = $row;
        }
        echo json_encode($rows);
    } else {
        echo json_encode(array());
    }
}
?>
