Description:
------------
The description of the return value refers to "elements", so the description does 
not specifically describe the degenerate case: when there are *no* elements.

PHP is not consistent in degenerate cases, so the reader might reasonably conclude 
that the result in the degenerate case might be NULL, FALSE or the empty string 
("").

In PHP 5.2, at least, the return value for the degenerate case is the empty 
string.

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.

Added extra example to show what will happen.
