Sorry to suggest this but is it just possible that the 'data' object you are
doing a strlen on is not null terminated or in fact contains earlier null
characters which are terminating your effort. I have made this mistake several
times when using mysql_escape_string. Now to avoid it I just use pointer
arithmetic.
