array_multisort ()

[Schraalhans Keukenmeester]

I'm having a hard time getting to grips with this function.

I have an array shaped like this:

$dircontents[0]['filename'] ='index.html'
$dircontents[0]['owner'] = 'www'
$dircontents[0]['group'] = 'www'
$dircontents[0]['type'] = 'file'

$dircontents[1]['filename'] ='images'
$dircontents[1]['owner'] = 'www'
$dircontents[1]['group'] = 'www'
$dircontents[1]['type'] = 'dir'

etc.

'type' can be any of {dir,file,link}

How do I get the array sorted, alphabetically, first by type, then filename?
My attempts sofar have lead to a seemingly unsorted array, not even
close to anything recognizable. Is array_multisort () even what I should
be looking for?

Help appreciated!
Sh.

Try usort() instead:

function cmp($a, $b) {
if($a['type'] < $b['type'])
return -1;
elseif($a['type'] $b['type'])
return 1;
elseif($a['filename'] < $b['filename'])
return -1;
elseif($a['filename'] $b['filename'])
return 1;
else
return 0;
}

usort($dirconte nts, 'cmp');

Great! That's what I needed indeed. Somewhere in the back of my head...
Thanx Zeldor!

Had to rewrite it a little since I usesd strings. Final version, in case
someone else likes to use it as well:

function cmp($a, $b) {
$retval = strcmp($a['type'],$b['type']);
if ($retval === 0)
$retval = strcmp($a['filename'],$b['filename']);
return $retval;
}
usort($this->dircontents, 'cmp');

Again, thanks for the pointer!
