单独调用头像方法
$v['uid']为循环中用户的id
单独调用，可以根据用户登录id $uid
<?php $user = user_read_cache($v['uid'])?>
<?php echo $user['username']?> 会员名称
<?php echo $user['gid']?> 会员用户组
<?php echo $user['email']?> 注册邮箱
<?php echo $user['threads'];?> 发帖总数量
<?php echo $user['posts'];?> 回帖总数量
<?php echo $user['golds'];?> 会员金币数
<?php echo $user['credits'];?> 会员积分
//具体可以看数据库表user​
