Have you thought about swapping the elements, it's quite simple, I don't
know about more complicated methods using pointers
here's the code:
$layer is the array -
$currPos = array_search($HTTP_POST_VARS["selLayer"], $layer);
$temp = $layer[$currPos];
$layer[$currPos] = $layer[$currPos-1];
$layer[$currPos-1] = $temp;
> My example wasn't good.
>
> I have a array of objects and want change its positions.
>
> $array = (obj2, obj1, obj3) --> $array = (obj1, obj2, obj3).
>
> Like TStringList.Exchange in Delphi.
>
> Sort() don't work in this case, because I want sort based in a attribute of
> the object.
