Are there any tutorials available for implementing a feature to display logged-in users in PHP?

To display logged-in users in PHP, you can utilize sessions to store user information after they log in. You can then retrieve this information to display the logged-in user's details on the webpage. 

<?php
session_start();

if(isset($_SESSION['user_id'])) {
    echo "Welcome, ".$_SESSION['username']."!";
} else {
    echo "You are not logged in.";
}
?>
