The example in this article describes the method of checking the ID of the current Session in php. Share it with everyone for your reference. The details are as follows:
There are two ways to get the user's session id. The first is to use the session_id() function, and the other is to use the built-in constant SID. SID contains the session id and session value
<?php session_start(); print("<html><b>"); $sid = session_id(); print("Session ID returned by session_id(): ".$sid."\n"); $sid = SID; print("Session ID returned by SID: ".$sid."\n"); $mysite = $_SESSION["mysite"]; print("Value of mysite has been retrieved: ".$mysite."\n"); print("</b></html>\n"); ?>
I hope this article will be helpful to everyone’s PHP programming design.
