checking for an integer

[Anon]

Is there a way to wheck wether the number inside a variable is an integer or not?

[kid_c]

if (gettype($variable)=="integer")
echo "its an integer!";
else
echo "its not an integer!";

Thanks. It doesn't works like I wish it did though. When the number is entered in a form, gettype returns "string".
Any idea?

Does anyone know the best way to solve this? Presumably everything from a ftext box is a string, so how can we chech that it is a number?
