A few questions from newbee

Hi,
Just started to use PHP and have a few
questions:
1. Is there something similar to ASP's Transfer/Execute
methods?
2. How to check whether mysql field has NULL value?
Especially, in mysql_fetch_row()?
3. How to create/use parameterized queries? I have
some experience in ASP/ADO and there I heavily use
parameters in query.

Thank you

One more question:
How to send binary files to output? E.g. I want
to send MP3 audio files from a script instead of
enabling direct access to these files for users.

barand

is '[man]header[/man]("location: another.php")' what you want?
[man]is_null[/man]
Just include a variable in the query
eg
$sql = "select * from table where afield = '$some_variable' ";
