The PHP manual is confusing me as far as sorting arrays goes. Heres the array I have set up, and I'd like to sort it based on the 'ext'. I refer to these like $files[12]["ext"] = "jpg"

Array
(
    [0] => Array
        (
            [name] => Empire.JPG
            [path] => ./files/Empire.JPG
            [size] => 191.01 kb
            [ext] => JPG
            [url] => localhost/wwwexplore/files/Empire.JPG
        )

    [1] => Array
        (
            [name] => Contact.gif
            [path] => ./files/Contact.gif
            [size] => 5.62 kb
            [ext] => GIF
            [url] => localhost/wwwexplore/files/Contact.gif
        )
...
)

I tried doing array_multisort($files["ext"]) but it says arg#1 must be an array. I'm not really sure how to sort this.

--Edit:

function cmp($a, $b)
{
    return strcmp($a["ext"], $b["ext"]);
}

printf(usort($files, "cmp"));

From the PHP manual, this has been bothering me for a long time but finally found it.

hi there,

a bit confused about what your doing - or trying to do...

you wish to sort by the ext... or group by them?

if your sorting by them.. is it alphabetically? - anyway, just sort() will do sorting by ext for you... http://php.net/sort

sounds more like your trying tyo group them though? let me know, we see what we can do ..
