Hi.
Think I've just stumbled upon a possible bug with is_int.
Hello Gareth,
if I'm not mistaken, $_REQUEST['days'] is a string, and unless you use
if (!is_int(intval($_REQUEST['days'])) || $_REQUEST['days'] < 0) {
I see no problem in is_int taking a string with numerals inside as not int.
the problem with this (which I did try before posting) is that of course
is somebody enters a text string, and you run intval() on that, it'll
return 1, not 0 as it has content. Only if it's empty would it return
zero, and as such is_int() will return 1/true again.
