Function

[unidox]

I have this function:

 

        private function getLong(&$string)
        {
            $data = substr($string, 0, 4);
            $string = substr($string, 4);
            $data = unpack('Vvalue', $data);
            return $data['value'];
        }

 

But I am getting the error: Warning: unpack() [function.unpack]: Type V: not enough input, need 4, have 0

 

The error line is $data = unpack('Vvalue', $data);

 

Whats wrong?
