Simple Login logout system using php

it should need 5 files for this login-logout system, they are

login/index page
datafetch/usercheck page
session/check page
welcome/profile page
logout page

the above files must me needed for this. we can named it as our wish. let see what i done here. and the database file is needed, if you have any doubt about insert coding check here for insert code

database name --> 2mylogin
table name --> login

DB.PHP

<?php 
$conn=mysql_connect('localhost','root','');
$db=mysql_select_db('2my4edge',$conn);
?>

INDEX.PHP

<?php
session_start();
?>
<form method="post" name="login" action="login.php">
<label for="name" class="labelname"> Username </label>
<input type="text" name="username" id="userid" required="required" /><br />
<label for="name" class="labelname"> Password </label>
<input type="password" name="password" id="passid" required="required"  /><br />
<input type="submit" name="submit" id="submit"  value="Login" />
</form>

in the index page we have to start the session, as the above mentioned. action is performed in login.php page.

LOGIN.PHP

<?php 
include('db.php');
session_start();
{
    $user=mysql_real_escape_string($_POST['username']);
    $pass=mysql_real_escape_string($_POST['password']);
    $fetch=mysql_query("SELECT id FROM `login` WHERE

                         username='$user' and password='$pass'");
    $count=mysql_num_rows($fetch);
    if($count!="")
    {
    session_register("sessionusername");
    $_SESSION['login_username']=$user;
    header("Location:profile.php"); 
    }
    else
    {
       header('Location:index.php');
    }

}
?>

if the session is registered then go to check the profile.php page there session.php file is included so the session is checked.

SESSION.PHP

<?php
include('db.php');
session_start();
$check=$_SESSION['login_username'];
$session=mysql_query("SELECT username FROM `login` WHERE username='$check' ");
$row=mysql_fetch_array($session);
$login_session=$row['username'];
if(!isset($login_session))
{
header("Location:index.php");
}
?>

check the session value is correct or not. if the session is value is not set, then again redirect to index.php page.

PROFILE.PHP

<?php
include("session.php");
?>

<h3 align="center"> Hellow <?php echo $login_session; ?></h3> 
<h2 align="center" >Welcome to login system</h2> 

<h4 align="center">  click here to <a href="logout.php">LogOut</a> </h4>

assign the logout.php page in the profile.php page.

LOGOUT.PHP

<?php
session_start();
if(session_destroy())
{
header("Location: index.php");
}
?>

in the logout.php page, we should unset or destroy the session value as the above you seen. then locate to index.php page.
and we should have to start the session in all the page.
