有时候数据库中存了汉字，取出来之后变成了乱码，可以用urlencode、urldecode这两个函数来解决这个问题，例如：
$statuses=M('information_sheet')->where(array('Id'=>$newsid))->field('List_ID,Id,CreateDate,Theme,pic_urls')->find();我从表information_shee中取出了List_ID,Id,CreateDate,Theme,pic_urls这几个字段的数据，其中Theme这个字段的数据是汉字，如果我不做处理，直接echo json_encode()输出的话，就会得到乱码，可以这样解决：
$statuses[0]['Theme']=urlencode($statuses[0]['Theme']); 用urlencode对中文进行编码
输出的时候为：
echo urldecode(json_encode($statuses)); 用urldecode解码，就可以得到正确的中文了
