Password Protection

[Anon]

Ive got a text file that looks like this:

fred fredd [e-mail]

i also have a page with a html form on it
that has two text boxes on it. One user name and one password. How do i scan the text file and say if the contents of the text file equals what you put in the text boxes?

Please help me!

$user = "username";
$pass = "password";
$login = false;
$file = file("yourfile.txt");
while(list($num,$line) = each($file))
{
$arr = explode(" ",$line);
if($arr[0] == "username" && $arr[1] == "password")
{
$login = true;
break;
}
}
if($login == true)
{
echo "you are in !"
}
