I am creating an array of sessions
$_SESSION['results'][]
There may be up to 7 and I need to know why do I always get the
notice'Undefined index: results in...'?
How do I define or initialise the array if it only gets set once the form
has been posted (an answer has been given) on the page.
Is there a way to count/output (FOR EACH?) a set of session arrays like
this?
Before you try to access the $_SESSION['results'] array, do this...
if (!isset($_SESSION['results'])) $_SESSION['results'] = array();
As far as counting and outputting a session array there is nothing
special about them - they are the same as any other array variable. This
means you can use foreach, print_r, var_dump, etc on them.
