[Solved] How to tell who is logged in PHP? [closed]

$_SESSION

A session is a way to store information (in the form of variables) to be used across multiple pages.

<?php 
 // this line starts the session and must be present in any page where you need to set or retrieve a session variable
 session_start(); 
 
 // this sets variables in the session 
 $_SESSION['userid']='123'; //obv it will be dynamic
 
 // this retrieves the value set earlier
 echo $_SESSION['userid'];
 ?>

So you can check on every page if the userid exist in the database you can fetch its record.
