如何使用 PHPSESSID 读取会话

Question

I Know A PHPSESSID in the server how can i read a session variable that is set to a PHPSESSID ( i don't want to use $_SESSION because i don't want start session in this thread ) i only want read session data with using PHPSESSID ?? PHP :

<?php
namespace MyApp;
class readSession extends \Thread {
    private $sess_id,$data_name;
    public function __construct($SESSID,$data_name){
        $this->sess_id = $SESSID;
        $this->data_name = $data_name;
    }
    public function run(){
        $data = $this->readSession($this->sess_id,$this->data_name);   
    }
    private function readSession($SESSID,$data_name){
        session_id($SESSID);
        session_start();
        $temp = $_SESSION[$data_name];
        var_dump($_SESSION);
        session_destroy();
        return $temp;
    }    
}

i write this code to read users session's data but it remove the users session data

First of all, reading another user's session data is a horrible idea. If you need to have shared access to that data - don't store it in the session.

Secondly, reading another doing it via session_start() with the same session ID is an even worse idea - that way you are effectively acting as that user. There's no easy/reliable way to read session data without intercepting it, but that's not by accident, it's exactly because you shouldn't do it.

That being said, don't call session_destroy() and the user's data won't be removed ... destroy means destroy. If you're looking for a way to just close a session, that's session_write_close() .
