Well, I was wondering if anyone could give me a script I can use to get a entered value from a post form (e.g Username) and check to see if the username exists in a plain txt file I have with usernames separated by a line break, thanks in advanced.

This should work, assuming that each line is only the username.

$filename = "path/to/file.txt";
$username = $_POST['username'];

$file = file($filename);
if (in_array($username, $file)) {
  ...code for when the username is in the file...
} else {
  ...code for when the username is not in the file...
