PHP: Is_numeric returns false on 0

Is_numeric()

as well as

is_int()

returns false if the value is 0. What can i do instead to verify that a specific value is numbers only in PHP?

Are we heading straight for the Regular Expressions camp, or are there some nice, handy feature for this out there already?

Thanks!
