Let's say user A and user B submitting purchase order form with "order.php"
at the same time, with method=post action='confirmation.php'.
(1) Will $_POST['order'] submitted by user A replaced by $_POST['order']
submitted by user B, and the both user A & B getting the same order, which
is made by user B? Why?
(2) Since $_POST['xxx'] is superglobal array, will $_POST['order'] read
by users other than A & B? In shared hosting server environment, are all
domains hosted within that server using the same $_POST array? Can $_POST
array accessible by all domains even if not from the originating domain?
Thx for clarification!
