Protect a PHP page the easy way…

Updated code:
Have you ever wanted to protect a PHP page to prevent people from viewing sensitive information?
Well I haven't but that doesn't stop me showing you how to do it if you ever need to ๐Ÿ˜€ .
The code below is extremely simple indeed. Anyone with a basic PHP understanding will see how simple it is.

All you have to do is paste the code below to the top of your PHP page and change these values:


Here is the code that I wrote, enjoy.

        session_start(); //initiates the sessions
        if      ($_POST['submit'])//checks to make sure the login form has been submitted
        $pass = "YOUR PASSWORD HERE";
        $user = "YOUR USERNAME HERE";
        if      ($_POST['pass'] == $pass && $_POST['user'] == $user)//checks if the password submitted by the user matches the password stored in the $pass variable
        $_SESSION['access']     = 1;//if login is successful create a session that can be authenticated
        header("Location: " . $_SERVER['PHP_SELF']);//reload the page. The page will now not load the login form (see the first if condition)
        else// if password is incorrect reload the login form
        header("Location: " . $_SERVER['PHP_SELF']);
        else if (!$_SESSION['access'])//if the "access" session is not accessible show the form (not logged in)
        <form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
        <table align="center" cellpadding="3" cellspacing="3">
        <td bgcolor="#F7F7F7">Username:</td>
        <td bgcolor="#F7F7F7"> <input name="user" type="text" /></td>
        <td bgcolor="#F7F7F7">Password</td>
        <td bgcolor="#F7F7F7"><input name="pass" type="text" /></td>
        <td colspan="2" bgcolor="#F7F7F7"><div align="center">
        <input name="submit" type="submit" value="Login">

What is interesting about this code is that you don't need to keep logging in everytime you return to the PHP page. It stores your valid login session :) .

Feel free to post a comment about the simple script, or indeed ways to improve it.

You may test the script here
Username: username
Password: pass

    You should comment on the lines and specify which line takes you to the auth page and which takes you to a pass incorrect page.

    Nice simple script though

    As this is a simple script, to add the functionality to logout would ruin its simplicity. As a result you will be logged out when your servers sessions are set to timeout. When they timeout, you will have to login again.
