You won't be able to use array_multisort() to do this, as your indexes are
the wrong way round. It looks to me like the only solution is using usort()
on $myarray, with a callback function that sorts on the [EXTENSION] element;
so, something like:
function compare($a, $b) {
return $a[EXTENSION]==$b[EXTENSION]?0:($a[EXTENSION]<$b[EXTENSION]?-1:1)
}
usort($myarray, "compare");
Cheers!
