[FX.php List] Record Count after the fact- Revisted

Sorry for the delay in responding.
A question regarding Dan's warning about putting data into SESSION Vars...
My choice is to put the array data (from the secondary query request
handled by PHP and not FMP) into either a regular variable
($temp_array) or a SESSION variable ($_SESSION['temp_array']), right?
Is there a difference between the handling of these two types, as Dan
suggested? Does the regular array stay on the web server but the
SESSIOn array travel to the browser each time?
Reviewing....For the initial search, it sounds like I will perform
the first query to FileMaker, perform the second half of the query in
PHP, store the results in the array, display results from the first
page (records 1 - x) from the array. Request for records from
subsequent pages will skip the FMP query and sub php query, and
extract data directly from the array using skipsize to grab the right
set of records.
Back to the question on regular array versus SESSION array: Will the
regular array be persistent from pages to page or am I forced to use
a SESSION array to access the array data?
Phew!
