// First check if it's a numeric value as either a string or number
    if(is_numeric($int) === TRUE){

        // It's a number, but it has to be an integer
        if((int)$int == $int){

            return TRUE;

        // It's a number, but not an integer, so we fail
        }else{

            return FALSE;
        }

    // Not a number
    }else{

        return FALSE;
    }

Also, instead of getting the variable as 

$my_var = $_POST["value"];

try this instead to see if the value is really passed.

$my_var = $_REQUEST["value"];

Variables transmitted by a POST request are strings, so you're calling is_int() on a string which returns false.

You may use is_numeric() or filter_var() instead or simply cast your variable to an integer.
