scanning a .txt

[Anon]

im making a login script and the usernam and password is in the file named pass69.txt... and it is set like so:

username password
username2 password2

is there a way to tell the form that it is set up like that and have it scan the .txt untill it find what is typed in the form text box named username and one named password?

Firstly, I'd look at fopen to open the .txt file:
http://www.php.net/manual/en/function.fopen.php

Secondly, read the file into an array:
http://www.php.net/manual/en/function.file.php

Thirdly, once you have the file contents in an array, scan through the array to find what you're looking for:

while(list($key, $value) = each($array))
{
print "$key ==> $value";
}

Hope that gets you started
