什么是PHPSESSID以及它为何没有进入Localhost，我可以将它用于任何加密密钥[关闭]

Question

What is PHPSESSID and why it is not getting in Localhost and can I use this for any encryption Key?

I am using my own encryption and decryption function

and I want one common key for each session so can I use PHPSESSID as a key for each session

and if yes then in Local I am not getting this key in request

NOTE: I can not Use session because at this stage I have not set LOGIN to system

If you want to get session id then you can get from below code.

<?php
session_start();
$sid = session_id();
echo "Session ID returned by session_id(): ".$sid."<br>";

It will be identify the unique user.
