Have you tried user custom examples/functions from the array_merge page? http://php.net/manual/en/function.array-merge.php

There seem to be quite a few examples that might fit your bill. One suggestion for keeping keys (no renumbering) is to use the + operator

$result = $x1 + $x2 (where x's are arrays)
