PHP Infinite-level data JSON format and JS parsing _php instance

Flash needs JSON format data, so, there is the following code: (PHP implementation, C # Similar, JSON library to go down to it ~ ~)
Copy CodeThe code is as follows:
--Query user downline information, return JSON, for Flash
if (!empty ($_get[' action ')) &&!empty ($_get[' invite '])) {
Fixed parameter request will return information
if ($_get[' action ']== ' GetInfo ' &&$_get[' invite ']==1 ') {
Data entity, an entity class
Class ucinvite{
---Display of data information
Public $fuid; User ID
Public $funame; User name
Public $furl; User space Address
---Display of data information
Public $fchilds; Sub-class Collection
}
$invitecount = 0; Total number, used to record total number of downline
Recursive implementation method
function Getshowtreeinvite ($uid) {
Global $_sglobal, $invitecount;
Organization SQL statement and query, table Fuid is offline Id,uid is the parent id,fusername is the user name
$INV _sql = "Select Fuid,fusername from". Tname ("Invite"). "Where uid =". $uid;
$INV _query = $_sglobal[' db ']->query ($inv _sql);
The following table and the returned array
$index = 0;
$inviteTree = Array ();
$invitezcount = 0; The number under each sub-class
Loop to add information to an array
while ($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 '];
Call yourself, recursively query subclass information
$ui->fchilds=getshowtreeinvite ($v [' fuid ']);
Insert in the returned array
$inviteTree [$index]= $ui;
$index + +;
$invitecount + +;
$invitezcount + +;
}
Record the number of downline in the current downline
$inviteTree [' invitezcount '] = $invitezcount;
Returning array information
return $inviteTree;
}
$fuid = Empty ($_get[' Fuid ')? $space [uid]:$_get[' Fuid '];
Queries information based on the current logged-in user ID and returns a collection
$inviteTree = Getshowtreeinvite ($fuid);
Record total number of downline
$inviteTree [' invitecount '] = $invitecount;
Introduction of the JSON Library, here is Services_json
Because it is not certain that the server is PHP5.2 or above, it does not use its own JSON function
Require_once ('.. /plugins/json/json.php ');
JSON output
$json = new Services_json ();
echo $json->encode ($inviteTree);
Exit
}else{
Echo ' request parameter Error! ';
Exit
}
}
--Query user downline information, return JSON, for Flash

The above code returns a JSON string such as:
{' 0 ': {' fuid ': ' 950 ', ' funame ': ' Guo Zi original ', ' furl ': '/home/space.php?uid=950 ', ' fchilds ': {' Invitezcount ': 0}}, ' Invitezcount ': 1, ' Invitecount ': 1}
Only one is queried here.
Next use JS for the following parsing:
Copy CodeThe code is as follows:

In this way, two infinite-level operations are completed, resulting in:
