I have a problem with login issue that when i loggin as student from index.php it should bring me to student_home php.. but it doesnt show anything and just bring me to index.php back.. i mixed up about header and session part..

my index.php

<?php
    include('header.php');
    //Start session
    session_start();
    //Unset the variables stored in session
    unset($_SESSION['id']);
    ?>
    <body>

        <?php include('navhead.php'); ?>

When working with sessions, you always have to put the session_start() before any output to the browser. Unfortunately, in this case, you've put session_start() after you called header.php, which does output to the browser...

...Also... you use mysql_ functions which are deprecated and might not work in the future. So try using msqli_ functions or PDO - Click Here
