dedecms会员系统开发

// 示例代码：检查数据库连接
$cfg_dbhost = 'localhost';
$cfg_dbname = 'dedecms';
$cfg_dbuser = 'root';
$cfg_dbpwd = 'password';

$conn = mysqli_connect($cfg_dbhost, $cfg_dbuser, $cfg_dbpwd, $cfg_dbname);

if (!$conn) {
    die('数据库连接失败: ' . mysqli_connect_error());
}

// 示例代码：检查会员权限
$member_id = 1;
$sql = "SELECT * FROM `dede_member` WHERE `id` = $member_id";
$result = mysqli_query($conn, $sql);

if ($result && mysqli_num_rows($result) > 0) {
    $row = mysqli_fetch_assoc($result);
    $user_type = $row['usertype'];
    // 根据$user_type设置权限
}

// 示例代码：使用Redis缓存
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);

$key = 'member_info_' . $member_id;
if ($redis->exists($key)) {
    $member_info = json_decode($redis->get($key), true);
} else {
    $sql = "SELECT * FROM `dede_member` WHERE `id` = $member_id";
    $result = mysqli_query($conn, $sql);
    if ($result && mysqli_num_rows($result) > 0) {
        $member_info = mysqli_fetch_assoc($result);
        $redis->setex($key, 3600, json_encode($member_info));
    }
}
