Question

I am trying to make sure the GET string is set in the URL and that it’s value is an integer, but I can’t get this to work.

if (isset($_GET['allusers']) && is_int($_GET['allusers'])) {

    echo "works";

}

Am I doing something wrong with my parentheses?

Answer 1

A $_GET variable can’t be an integer. It’ll always be a string.

To test is it’s a numeric string, use is_numeric():

if ( isset($_GET['allusers']) && is_numeric($_GET['allusers']) )
{
    echo "works";
}
