That is the way it's meant to be done.
is_int() really checks for the dataTYPE and not the CONTENTS (of course
the contents depend on the type, e.g. in an int you won't find a string).
giving is_numeric() and the ctype functions strings as argument actually
check for the CONTENTS (in different ways).
is_int(1) => true
is_int("1") => false
is_numeric(1) => true
is_numeric("1") => true
I hope now everything is clear for everybody.

P.S.: I think the general/help lists are more appropriate for these kind
of problems before asking internals.
P.P.S.: Sorry for potential spam, but I thought it is necessary to clear
it up once and for all.
