The functions is_int() and is_long() don't return true if the given argument is a variable:

echo is_int(12345);
--> 1

echo is_int("12345");
--> (nothing returned!!)

$abc = "12345";
echo is_int($abc);
--> (nothing returned!!)

echo is_int("abcdef");
--> (nothing returned!!)

$abc = "abcdef";
echo is_int($abc);
--> (nothing returned!!)

Is this behaviour a bug or a feature?

It isn't returning nothing, it is returning false which is an empty string.  No bug here.
