PHPとVue：会員ポイントの有効期限延長機構の実装方法

CREATE TABLE members (
    id INT PRIMARY KEY AUTO_INCREMENT,
    name VARCHAR(255) NOT NULL,
    points INT NOT NULL,
    expire_date DATE NOT NULL
);

// 获取当前时间
$currentDate = date('Y-m-d');

// 查询会员信息
$query = "SELECT * FROM members";
$result = mysqli_query($connection, $query);

// 遍历每个会员
while ($row = mysqli_fetch_assoc($result)) {
    $expireDate = $row['expire_date'];
    $points = $row['points'];
    $id = $row['id'];

    // 如果当前时间大于有效期并且积分大于0
    if ($currentDate > $expireDate && $points > 0) {
        // 将有效期延长一年
        $newExpireDate = date('Y-m-d', strtotime('+1 year', strtotime($expireDate)));
        
        // 更新数据库中的有效期字段
        $updateQuery = "UPDATE members SET expire_date = '$newExpireDate' WHERE id = '$id'";
        mysqli_query($connection, $updateQuery);
    }
