PHP unlimited data JSON format and JS parsing_PHP tutorial
Flash requires data in JSON format, so the following code is available: (PHP implementation, similar to C#, download the JSON library yourself~~)
//--Query user offline information and return JSON for flash
if(!empty($_GET['action'])&&!empty($ _GET['invite'])){
//Only fixed parameter requests will return information
if($_GET['action']=='getinfo'&&$_GET['invite']==1) {
//Data entity, an entity class
class UcInvite{
//---Data information for display
public $fuid; //User id
public $funame; / /Username
public $furl; //User space address
//---Data information for display
public $fchilds; //Subclass collection
}
$invitecount = 0; //Total quantity, used to record all offline quantities
//Recursive implementation method
function GetShowTreeInvite($uid){
global $_SGLOBAL,$invitecount;
//Organize sql statements And query, fuid in the table is the offline id, uid is the parent id, and 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 return array
$index = 0;
$inviteTree = Array() ;
$invitezcount = 0; //The number under each subcategory
//Loop to add information to the array
while($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 to recursively query subclass information
$ui-> fchilds=GetShowTreeInvite($v['fuid']);
//Insert into the returned array
$inviteTree[$index]=$ui;
$index++;
$invitecount++;
$invitezcount++;
}
//Record the number of current downlines
$inviteTree['invitezcount'] = $invitezcount;
//Return array information
return $inviteTree;
}
$fuid = empty($_GET['fuid'])?$space[uid]:$_GET['fuid'];
//Query information based on the current logged in user ID and return A collection
$inviteTree = GetShowTreeInvite($fuid);
//Record the total number of offline entries
$inviteTree['invitecount'] = $invitecount;
//Introduce the json library, used here It is Services_JSON
//Because we are not sure that the servers are all PHP5.2 or above, we do not use the built-in 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 offline information and return JSON for flash
The above code returns a JSON string , such as:
{'0':{'fuid':'950','funame':'Guo Ziyuan','furl':'/home/space.php?uid=950','fchilds':{ 'invitezcount':0}},'invitezcount':1,'invitecount':1}
Only one is queried here
Next, use JS to perform the following analysis:
In this way, the two infinite-level operations are completed. The result screenshot:

Arrays can be stored in PHP sessions. 1. Start the session and use session_start(). 2. Create an array and store it in $_SESSION. 3. Retrieve the array through $_SESSION. 4. Optimize session data to improve performance.

PHP session garbage collection is triggered through a probability mechanism to clean up expired session data. 1) Set the trigger probability and session life cycle in the configuration file; 2) You can use cron tasks to optimize high-load applications; 3) You need to balance the garbage collection frequency and performance to avoid data loss.

Tracking user session activities in PHP is implemented through session management. 1) Use session_start() to start the session. 2) Store and access data through the $_SESSION array. 3) Call session_destroy() to end the session. Session tracking is used for user behavior analysis, security monitoring, and performance optimization.

Using databases to store PHP session data can improve performance and scalability. 1) Configure MySQL to store session data: Set up the session processor in php.ini or PHP code. 2) Implement custom session processor: define open, close, read, write and other functions to interact with the database. 3) Optimization and best practices: Use indexing, caching, data compression and distributed storage to improve performance.

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.

The session realizes user authentication through the server-side state management mechanism. 1) Session creation and generation of unique IDs, 2) IDs are passed through cookies, 3) Server stores and accesses session data through IDs, 4) User authentication and status management are realized, improving application security and user experience.
