Allright, it turns out that 0 ( zero ) is seen as empty ...

http://www.php.net/empty

Here is a list of considered empty types and values:

Return Values

Returns FALSE if var has a non-empty and non-zero value.

The following things are considered to be empty:

  • "" (an empty string)
  • 0 (0 as an integer)
  • "0" (0 as a string)
  • NULL
  • FALSE
  • array() (an empty array)
  • var $var; (a variable declared, but without a value in a class)
