<?
$password_file = "/pass.txt";
$username = $_POST['login'];
$password = $_POST['password'];
if($_POST['checkpass']) {
if(empty($username) OR empty($password)) {
echo "Username and Password is required.<br />Use your browser Back
button to try again";
exit;
} else {
}
}
function check_pass($login, $password) {
global $password_file;
if(!$fh = fopen($password_file, "r")) {die("<P>Could Not Open Password
File - Contact the Webmaster");}
$match = 0;
$password = md5($password);
while(!feof($fh)) {
$line = fgets($fh, 4096);
$user_pass = explode(":", $line);
if($user_pass[0] == $login) {
if(rtrim($user_pass[1]) == $password) {
$match = 1;
break;
}
}
}
if($match) {
return 1;
}
else {
return 0;
