If it indeed is the first element, then you can use reset (and for the last
element end) but there is no such functionality for returning the n'th
element.

echo reset(functioncall());

http://fi2.php.net/manual/en/function.reset.php
reset() rewinds array's internal pointer to the first element and returns
the value of the first array element, or FALSE if the array is empty.
