What about using an array as your session variable, and loop through the
array:

foreach($_SESSION['fair_name'] as $val) {
	echo $val . ': success';
}

Subject: [nycphp-talk] accessing $_SESSION elements

Hi all,

I'm trying to avoid a bunch of if/then statements by looping through
$_SESSION.  I hit a roadblock that I can't seem to get around.  Here is a
simple piece of code which I think gets to the heart of the problem:

$begin=1;
if(isset($_SESSION['$begin_fair_name']))
{
   echo "success";
}

Of course, this works:
if(isset($_SESSION['$1_fair_name']))
{
   echo "success";
}

BUT, I have between 1 and 10 fair_name fields (i.e. 1_fair_name,
2_fair_name) coming from the form.  It would be much more efficient if I can
loop through and perform operations as opposed to a bunch of if/then
statements referring to specific fair_name fields.  Obviously the problem is
with using a variable inside the array and I haven't been able to figure out
how to work around it.

Trying to keep it brief here, but please let me know if further details
would be helpful.  I would appreciate any tips or suggestions.

Thanks!

-Aaron
