is_int odities

[Perad]

$poll = $_GET['poll'];
$user_id = $_GET['user'];
if (is_int($poll)) {

 

$poll = 13

 

The if code does not work.

 

If I change the code to (is_int(13)) Then it works..

 

Any ideas why this is?

try using is_numeric instead.

 

sometimes the php considers your number a string and not an integer, depending on how it was assigned to the variable

I would either type cast it with (int) or use ctype_digit if validating user input personally

GET and POST values are always strings, therefore is_int fails.

Also, is_numeric will accept scientific and hexadecimal notation. If you only want to allow integers, use ctype_digit.
