PHP Question

I am trying to make php Readline where it reads from line 2 and loops to the end.

> if (isset($_POST['oldpass'])) {
> 
> $username=readLine("/home/logins/".$_SERVER['REMOTE_ADDR'],
> 1); $handle =
> @fopen("/home/users/".$username.".txt",
> "r"); // Open file form read. if
> ($handle) { while (!feof($handle)) //
> Loop til end of file. {
> fclose($handle); // Close the file. }
> $password=readLine("/home/users/".$username.".txt",
> 1);   if ($password==$_POST['oldpass'])
> {         if
> ($_POST['newpass']==$_POST['repass'])
> {
>           $file1=fopen("/home/users/".$username.".txt",
> "w");             fwrite($file1,
> $_POST['newpass']."\n");
>           fwrite($file1, $handle);
>           fclose($file1);

That is what I got so far. Please help. Thank you.
