====== How the php array_multisort function works ======

The array_multisort function in php allows you to sort several arrays at the same time. How it works is:

  - Sort first array by key value (depending on arguments)
  - If there are any identical keys in the first array, sort these by the keys in the second array (assuming it is specified)
  - etc.


The [[http://www.php.net/manual/en/function.array-multisort.php|documentation]] for this isn't particularly clear.
