这段代码的作用是从数据表 `data_user_item` 中查询指定用户的未使用的物品信息,并通过循环将每个物品对应的新闻信息从数据表 `data_news_item` 中查询出来,最终返回一个包含所有物品对应新闻信息的数组 `$data_news_item`。其中 `$openid` 是从 GET 请求中获取到的用户唯一标识,`$uid` 是通过 `$openid` 查询得到的用户 ID。需要注意的是,这段代码中 `$uid` 被硬编码为了 1,而非通过 `$openid` 查询得到的真实用户 ID,这可能是为了测试或者其他目的而做出的临时修改。

为以下代码注释:function user_fetch($openid){ global $_W; if((int)$openid){ $user = pdo_get("drawlots_user",['id'=>$openid]); } else{ if(empty($openid)){ $openid = $_W['openid']; } $user = pdo_get("drawlots_user",['uniacid'=>$_W['uniacid'],'openid'=>$openid]); } return $user; }
这段代码是一个函数,函数名为`user_fetch`,它接收一个参数`$openid`。该函数首先通过`global $_W`声明全局变量`$_W`,然后判断`$openid`是否为整数类型,如果是,则从数据库表`drawlots_user`中获取`id`等于`$openid`的记录,并将其赋值给变量`$user`。
如果`$openid`不是整数类型,则会检查`$openid`是否为空,如果为空,则将全局变量`$_W`中的`openid`赋值给`$openid`。之后,函数会从数据库表`drawlots_user`中获取`uniacid`等于`$_W['uniacid']`且`openid`等于`$openid`的记录,并将其赋值给变量`$user`。
最后,函数返回变量`$user`。

"\n"; } echo $str; exit; 在导出前每个字段都有数据,导出后有一条数据的laiyuan为空
根据你提供的代码,看起来问题可能出现在 `$val['laiyuan']` 字段的处理上。请尝试以下调整:
1. 检查 `$val['laiyuan']` 字段的值是否为空。可以在循环中使用 `var_dump($val['laiyuan'])` 来确认该字段的值是否存在。
2. 确保 `$val['laiyuan']` 字段的值是正确的编码格式。可以尝试将其转换为正确的编码格式,例如 `iconv("UTF-8", "GB2312", $val['laiyuan'])`。
3. 如果 `$val['laiyuan']` 字段的值包含特殊字符或 HTML 标签,可以尝试使用 `htmlspecialchars` 函数进行转义,例如 `$laiyuan = iconv("UTF-8", "GB2312", htmlspecialchars($val['laiyuan']))`。
确保在对字段进行处理之前,数据在数据库中是正确的。如果问题仍然存在,请提供更多关于该字段的信息,例如数据类型、示例值等,以便我能够更具体地帮助你解决问题。
