Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

"empty() returns FALSE if var has a non-empty and non-zero value." http://php.net/empty

I've found the explanation that empty() should work like this (however pre 4.3.10 empty in case like that would  return false as I would expect). 0 in a string is not an empty value, and in my opinion empty should return false in case like this. But thats my thinkin :)
