encode(0xffffffff) returns empty string

[ifduyue]

To reproduce:

<?php

require_once 'vendor/autoload.php';
$hashids = new Hashids\Hashids();
$id = $hashids->encode(0xffffffff);
var_dump($id);

echo "Hashids.php version is ".Hashids\Hashids::VERSION."\n";

Output:

string(0) ""
Hashids.php version is 1.0.5

PHP version:

$ php -v

Do you have a 32-bit system? It might be too big of an int to handle, because this works on mine.
Try checking the upper Hashids limit with $hashids->get_max_int_value();

It's a 64-bit system. Sorry I didn't read through the readme. I install php-bcmath and the problem no longer exists.

Thanks for your time.

Cool. Glad you got it working.
