Sorting dirs and files

[Moonglobe]

the following function:

function wftp_dircmp_callback($el1, $el2)
{
    if (substr($el1['permissions'],0,1) === 'd')
    {
        if (substr($el2['permissions'],0,1) === 'd')
        {
            $eltest = array($el1['fname'],$el2['fname']);
            natsort($eltest);
            if ($eltest[0] == $el1['fname'])
            {
                return 1;
            }
            else
            {
                return -1;
            }
        }
        else
        {
            return 1;
        }
    }
    elseif (substr($el2['permissions'],0,1) === 'd')
    {
        return -1;
    }
    else
    {
        $eltest = array($el1['fname'],$el2['fname']);
        natsort($eltest);
        if ($eltest[0] == $el1['fname'])
        {
            return 1;
        }
        else
        {
            return -1;
        }
    }
}

is suppoed to be used in a uasort() callback. will someone please tell my why this does not sort directories 'naturally' at the top, and files 'naturally' below? $el1 and $el2 both look like e.g:

array
(
    [fname] => www
    [size] => 4096
    [permissions] => drwxrw-r--
    [owner] => moonglob
    [group] => moonglob
    [modtime] => Nov 2 12:28
)

can anyone help? the output looks like no sorting occured 🙁

You are returning 1 or -1 if both of the test items are not directories, this will change the ordering of the two elements, probably throwing off the sorting.

The function natsort($array) maintains the index association. For this code, usort($array, "strnatcmp") would work better.

ah, but you see, the indices are important. they are also the file names. actually......... hmmm.......... it's be a kludge but it might work..........

thx for the idea.........
