not that im aware of, even if you use the operator overloading extension, im
not sure youll find that ability.
I can use the BC library's math functions instead:

i dont know how bad that is really, i guess it depends on the distribution
scope of the application. if its in a controlled environment, id just say
install bcmath and forget it.
I can create an anonymous function:

well, youll just have to wait for 5.3 and its new lambda notation, youll be
able to do this (something close anyway :)),
array_map(function($a, $b) { return $a + $b; }, $array1, $array2);
it doesnt look like much difference here, but create_function() gets a lot
worse w/ functions any less trivial than adding 2 numbers.
Is there any simple clean way to do it? Thanks,
i think youre beating your head against the wall for no good reason. your
solutions are fine, just pick one and roll w/ it ;)
