That's not a bug, they're both the same number. Leading zeros are always ignored in number systems, and PHP doesn't attempt to format it assuming and specific word size. Try the same conversion in your computers calculator.
To format the number as you wish for output, use printf or sprintf to pad with leading zeros.
