and along the way i got this code;
// If we want more fields, then use, preupload.php?number_of_fields=20 $number_of_fields = (isset($_GET['number_of_fields'])) ? (int)($_GET['number_of_fields']) : 5;
ok, i know that the variable $number_of_fields was assigned by an isset which is from $_GET
which has a ternary condition.
now my basic question is what is an (int) doing inside a ternary condition operator?
what an (int) purpose?
thanks in advance.
