problems with session variables

[Japhy]

hello,
I am finding that setting session variables is very unreliable (for
me).

Am I doing something wrong with syntax :
$contnum = getrequest("ID1 ") ; (ID1 is passed in the URL)
$_SESSION['sess_contnum']= $contnum ;

My program will randomly start to fail.
If I echo $sess_contnum, sometimes it is set, sometimes not.

I am using Apache 2.0.53 as a web server. Are there any parameters I
should be aware of (more memory allocated for SV's or ?).

thanks for any help!

Japhy,

Are you calling session_start() at the *beginning of every page* which
uses sessions?

This *must* be done before *any* output is sent to the browser if you're
using cookie based sessions.

You shouldn't be using $x to access $_SESSION['x']. See

Re: problems with session variables

Thanks. That helped me solve my 'reliability' problem, and as stated,
is more secure.
