Note that concatenating with [code]+=[/code] operator will create a new array. If you want to append another array to an existing array, [method append_array] is more efficient.
[b]Note:[/b] Arrays are always passed by reference. To get a copy of an array which can be modified independently of the original array, use [method duplicate].
