Hello Mario,

Yes, rename your script as you wish it to be called and use .htaccess
or Apache main configuration files to tell that the file is to be handle
as PHP script. Make sure that the Content-Type header is set in the script
to application/octet-stream .

is_int does not tell if a string is an integer. It just tells if a varaible
is an PHP integer. If you read the data as a string it will always be a
string even if it contains digits.

To check if it is a valid integer I usually do it like this:

$value=intval($data);
if("$value"=="$data")
        echo "$value is an integer";

Keep in mind that there must be no spaces arround the integer data.
