[PHP3] 2 small questions... From: Mario Jorge Nunes Filipe (mjnf <email protected>)

Hello everyone

I have a couple of questions to pose to the fine people who lurk (or is
it lurke) arround this list.

Number 1 - I want to produce a CSV file of a set of records from a
database so that the users can import it into Excel (or similar). I
would like to know if there is a way i can force the browser to show a
file save dialog to save the file instead of showing the records on
screen and forcing them to save.

Number 2 - the very same files are going to be treated by the users and
then re-imported to the system. Each line has a student number, the
grade, and an adittional note. I read a line with fgets, then explode it
using "," as the separator. There is a possibilitie that the first
contains the headers instead of info, but it might not be there either.
So i thought about testing the first field by doing is_int($dados[0]).
$dados[0] is an integer (I insert into postgres on an int field and it
doesn't complain) but is_int returns nothing and neither does is_string
! So the question is : am i using is_int wrongly or is this pure and
simply broken (unlikely?)?

I'm using php 3.0.6!

Thank you very much!
