PHP Appending to MultiDimensional Arrays

Ack, the title of this post is a mouth full! Anyway, what does everyone recommend for appending new arrays to a multidimensional (3D) array in PHP? Best command or sample code should answer my question nicely.

I don't think in PHP you can even do dynamic arrays that are more than only linear (single dimension).
You may have some success if you use a database table or two instead since database table data is dynamic (of course).

PHP definitely has 3D / Multidimensional arrays, and I can create them easily enough. I just wanted an easy to perform append. I could read back the 3D array from the DB, add my new one, and then write back, but that is a bit clunky.

I'm looking for something like array_merge (but that one overwrites keys if they are named the same)...

I'd much prefer to use a new table and add records, 1 per entry... but I am working within a very bib and popular system, and that is also a secondary option (adding new tables). I may have to do one of the things I'm trying to avoid (read full array, add, write back / add another table), but only as a last resort.

I never said PHP didn't allow for 3D arrays. I said 3D arrays in PHP can't be dynamic. Only !D arrays can be dynamic in PHP. Unless "append" is something that we both understand in different ways in regards to arrays.

Maybe this user contribution to the php.net community can be helpful:

That user posted something interesting, but I don't know if that is what you need.

Thanks for your help everyone. I found the answer, and I feel pretty silly:
Adding to 3D arrays is as easy as adding to regular arrays!

$users[] = $newuser;

That's bloody it! Amazing, huh? If $users is a 3D array, and $newuser is an array, it just adds it to the 3D array like I need it to. When all else fails, try the simplest thing you can think of! Oh well, the 5-6 hours I spent researching this answered some questions I'll need to take care of later, and I learned a ton while at it.
