php 无限级数据JSON格式及JS解析
Flash需要JSON格式的数据,于是,就有了如下代码:(PHP实现,C#类似,JSON库自己去下吧~~)
复制代码 代码如下:
//--查询用户下线信息,返回JSON,用于flash
if(!empty($_GET['action'])&&!empty($_GET['invite'])){
//固定参数请求才会返回信息
if($_GET['action']=='getinfo'&&$_GET['invite']==1){
//数据实体,一个实体类
class UcInvite{
//---显示用的数据信息
public $fuid; //用户id
public $funame; //用户名
public $furl; //用户空间地址
//---显示用的数据信息
public $fchilds; //子类集合
}
$invitecount = 0; //总数量,用于记录全部下线数量
//递归实现方法
function GetShowTreeInvite($uid){
global $_SGLOBAL,$invitecount;
//组织sql语句并查询,表中fuid是下线的id,uid是父id,fusername是用户名字
$inv_sql = "select fuid,fusername from ".tname("invite")." where uid = ".$uid;
$inv_query = $_SGLOBAL['db']->query($inv_sql);
//下表及返回数组
$index = 0;
$inviteTree = Array();
$invitezcount = 0; //每个子类下的数量
//循环添加信息到数组
while($v = $_SGLOBAL['db']->fetch_array($inv_query)){
$ui = new UcInvite();
$ui->fuid = $v['fuid'];
$ui->funame = $v['fusername'];
$ui->furl = "/home/space.php?uid=".$v['fuid'];
//调用自己,递归查询子类信息
$ui->fchilds=GetShowTreeInvite($v['fuid']);
//插入返回的数组中
$inviteTree[$index]=$ui;
$index++;
$invitecount++;
$invitezcount++;
}
//记录当前下线的下线数量
$inviteTree['invitezcount'] = $invitezcount;
//返回数组信息
return $inviteTree;
}
$fuid = empty($_GET['fuid'])?$space[uid]:$_GET['fuid'];
//根据当前登录用户ID查询信息,并返回一个集合
$inviteTree = GetShowTreeInvite($fuid);
//记录总下线数
$inviteTree['invitecount'] = $invitecount;
//引入json库,这里用的是Services_JSON
//因为并不确定服务器都是PHP5.2以上版本,所以没有用自带的JSON函数
require_once('../plugins/JSON/JSON.php');
//json输出
$json = new Services_JSON();
echo $json->encode($inviteTree);
exit;
}else{
echo '请求参数错误!';
exit;
}
}
//--查询用户下线信息,返回JSON,用于flash
以上代码返回一个JSON字符串,如:
{'0':{'fuid':'950','funame':'郭梓原','furl':'/home/space.php?uid=950','fchilds':{'invitezcount':0}},'invitezcount':1,'invitecount':1}
这里只查询了一个
接下来用JS进行以下解析:
复制代码 代码如下:
这样,两个无限级的操作就完成了,结果截图:

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

What are the magic methods of PHP? PHP's magic methods include: 1.\_\_construct, used to initialize objects; 2.\_\_destruct, used to clean up resources; 3.\_\_call, handle non-existent method calls; 4.\_\_get, implement dynamic attribute access; 5.\_\_set, implement dynamic attribute settings. These methods are automatically called in certain situations, improving code flexibility and efficiency.
