Writing to specific line

[Noonga]

Does anyone know if its possible to write to a specific line, perhaps using fwrite() or something?

PHP Code:

<?php
    session_start();
    $id = "2";

So I can get PHP to write in $id from $POST or something.

line in a file?
line (record) in a database table?

Need more info as to what you are seeking to accomplish.
