Hi Bev,
Hope you’re doing well over there in Kentucky! You may not know that
I moved to Austin 2-1/2 years ago, so we’re not neighbors anymore…
So, my array has 11 elements to it, and x rows; is that considered a
2-dimensional array?

Hi Bob,
Good to see you got the handle of php arrays.
Note that what you are creating is a "two dimension" array. A one
dimension array is a simple list, just like what FM's List()
function creates, and a basic Value List. A two dimension array is
an array of arrays, like a spreadsheet, or an FM table. A three
dimension array is an array of arrays with an array as at least one
of the elements. An FM table with a repeating field could be seen
as a 3 dimension array.

Hey Bob,
Does anything come out of the session array at all? If not, the
session may not yet be started... Do you call session_start()
before doing anything else with the session? Also, have you
declared the 'student_array' element to be an array, like so:
$_SESSION['student_array'] = array();
Once you do that, option one in your question should work just fine...

OK, absolutely last question:
I’m storing the array in a session variable; I tried this:
$_SESSION['student_array'][] = array(…
and I tried this:
$_SESSION[‘student_array[]'] = array(…
but neither of those are correct; how do I add rows to an array
stored in a session var?

Yeah, you need an "as" clause in that foreach:
foreach($_SESSION['student_array'] as $student){
print_r ($student);
}
Howzzat?

I figured a foreach loop would be the way, but this doesn’t run:
foreach($_SESSION['student_array']){
print_r ($_SESSION['student_array']);
}
Missing something obvious, no doubt… ?

I was thinking I was going to initialize the array when the
site loaded, but hadn’t thought about just using isset().
Sometimes the easiest stuff makes me over-complicate…
Now to figure out how to return subsequent rows… ?

I like using isset($someVariable) to check whether something
exists. Avoids all sorts of mess =)
