Re: session array

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. -Stut
