Password protect PHP

//access.php

<?php
//put sha1() encrypted password here - example is 'hello'
$password = 'aaf4c61ddcc5e8a2dabede0f3b482cd9aea9434d';

session_start();
if (!isset($_SESSION['loggedIn'])) {
$_SESSION['loggedIn'] = false;
}

if (isset($_POST['password'])) {
if (sha1($_POST['password']) == $password) {
$_SESSION['loggedIn'] = true;
} else {
die ('Incorrect password');
}
}

if (!$_SESSION['loggedIn']): ?>

<html><head><title>Login</title></head>
<body>
<p>You need to login</p>
<form method="post">
Password: <input type="password" name="password"> <br />
<input type="submit" name="submit" value="Login">
</form>
</body>
</html>

<?php
exit();
endif;
?>


Then on each file you want to protect, put at the top:

<?php
require('access.php');
?>
secret text


You could add a logout.php page like:

<?php
session_start();
$_SESSION['loggedIn'] = false;
?>
You have logged out
