Bug description: array_combine issues warning on empty arrays
Description:
------------
array_combine issues a warning when empty arrays are passed as arguments,
I submit that empty arrays should be valid input for this function, and
the result should also be an empty array (rather than FALSE and a
warning).
On top of that, the warning is non-sensical, as it states that "Both
parameters should have number of elements at least 0"
Reproduce code:
---------------
$a = array();
$b = array();
$c = array_combine( $a, $b );
var_dump( $c );
Expected result:
----------------
array(0) { }
Actual result:
--------------
Warning: array_combine() [function.array-combine]: Both parameters should
have number of elements at least 0 in /var/www/vhosts/.../test.php on line

bool(false)
