This may be a silly question, but I can't spot and easy way to do it, I
want to check if the value inside a vriable is an integer. If I do
is_int($variable) I always get false, because this variable qwas read in
from a form so its a string, if I make the variable an integer using
settype() I just end up with 0 if it was invalid, the number otherwise. I
need something that will actually tell me if there the conversion was
successfull. Am I missing something?
Thanks,
Shaun
