Like @loustak said arrays are not officially supported by the current version of GD, and to be honest I don’t see the advantage in work in an older version of GD, because you’ll had to deal with a lot of bugs that have come fixed since then.
There are another ways to resolve the “array” thing in GD. There are ways to load and simulate arrays and work with a specific object of a collection.
A few days ago I released the source project for a small game of mine, there are some “array work-arounds” that maybe you can find useful.
You can download the source project from this thread: [url]Group-It source project released]
Hope it helps.
