how to reverse a 3d array?

[stuartc1]

I have an array like this:

$images[] = array('filename' => $f, 'width' => $width, 'height' => $height, 'size' => $size, 'date' => $date);

Which has been ordered by date, using the following function:

function multi_sort($tab,$key){
   $compare = create_function('$a,$b','if ($a["'.$key.'"] == $b["'.$key.'"]) {return 0;}else {return ($b["'.$key.'"] > $b["'.$key.'"]) ? -1 : 1;}');
   usort($tab,$compare) ;
   return $tab ;
}

multi_sort($images, "date");

All works great, but it's ordered with the oldest date first - I need to reverse the order of the array by date.

Any idea??

Change > to < ? Or swap -1 and 1? Maybe you want to add an extra parameter (defaulting to ASCENDING) to say which direction the sort should proceed in?
