$_SESSION['logged_in'] = true;
//login page is like this

//welcome page is like this
<?php
$_SESSION['logged_in'] = true;
if(empty($_SESSION['logged_in']) || $_SESSION['logged_in'] == ''){

Think about what you are doing here $_SESSION['logged_in'] = true;...

I am thinking that I am setting the session to true for when the user logs in. can you assist me f you have any know-how, please

You are setting it and then testing in an if statement. You need to set it after the user has logged in.

Given 0x01AA & ZurdoDev already shared the details, have a look at this to try and learn: PHP - Login Example - Tutorialspoint[^]

Login sample:

PHP

<?php
    $msg = '';
    
    if (isset($_POST['login']) && !empty($_POST['username']) 
       && !empty($_POST['password'])) {
		
       if ($_POST['username'] == 'tutorialspoint' && 
          $_POST['password'] == '1234') {
          $_SESSION['valid'] = true;
          $_SESSION['timeout'] = time();
          $_SESSION['username'] = 'tutorialspoint';
          
          echo 'You have entered valid use name and password';
       }else {
          $msg = 'Wrong username or password';
       }
    }
 ?>

Logout:

PHP

<?php
   session_start();
   unset($_SESSION["username"]);
   unset($_SESSION["password"]);
   
   echo 'You have cleaned session';
   header('Refresh: 2; URL = login.php');
?>

Would suggest, pick a book or any online tutorial (like above reference) to go through basic chapters, that would really help.
