read the manual entry first (see below) - and understand what the
function actually does - never just assume because its giving you the
result you want now that it will always work the way you expect.

you think???
hit the manual: http://www.php.net/array_merge
(thats 30 chars to type in the addressbar of your favorite browser and
then you'd be sure)
probably array_merge() will do what he wants but there maybe
side-effects that will bite him in the ass later on, same goes for my
(previous) suggestion of array_values() as it happens <blush>.
a tip for those who don't already know:
php.net (and its mirrors (I usually use nl2.php.net)) have a great
search mechanism:
http://www.php.net/<function-name>
replace <function-name> with the name of function your interested in and
boom your right at the page you need! actually other keywords work as
well. for instance:
need to know more about arrays: http://www.php.net/array
or mysql http://www.php.net/mysql
or overloading http://www.php.net/overload
even when you don't know the exact keyword to use, your guess will often
get you where you want!

nl2.php.net is the best php mirror out there *obviously*, nothing to do
with the fact that the guys that run it are friends of mine, or the fact
that they do such a great job at hosting alot of the sites I
build/run/own ;-) [www.nedlinux.nl: linux freaks with a lowlands twist]
