PHP sorting arrays by a Key

[CaShY]

Hi anyone know how to sort a multidimensional array by a key in php?


the data goes

Array [0] ( [id] => 1 [link] => link [weight] => 10 )
Array [1] ( [id] => 2 [link] => link [weight] => 1 )
Array [2] ( [id] => 3 [link] => link [weight] => 8 )
Array [3] ( [id] => 4 [link] => link [weight] => 10 )

I want to sort the array we shall call $links

by weight decending.

Looked everywere and i can't work it out any help out be great.

[Add]

foreach ($link as $val) {
     $sortarray[] = $val['weight'];
     $sortarray = array_reverse($sortarray, true);
}
array_multisort($sortarray,$link);

not tested...
