I have a flat file on the server which I append to from a HTML web form.
I need to delete the last line of the flat file before I append though.

How do i do that?

I have the following code. I''m not sure if it''s correct.

$pattern = "</member>"; // what I want to look for.
$ora_books = preg_grep($pattern, file(''/path/to/your/file.txt''));
