Help sorting a multidimensional array

[Receptional Andy]

I have an array that looks something like this:

Array
(
 [0] => Array
  (
   [score] => 50
   [name] => Widget
  )
 [1] => Array
  (
   [score] => 550
   [name] => Gadget
  )
)

Is it possible to sort this array via the value of [score]?

I've got as far as trying to use both array_multisort and usort, without really understanding how they work ;)

Thanks for any pointers :)

usort is a good way to do it. usort passes the outer array members to your function, and your function is supposed to return an integer that indicates whether the first argument is greater than, equal to, or less than the second argument. If you have:
function scoreAsc($a,$b) {
if($a['score'] == $b['score']) return 0;
if($a['score'] > $b['score']) return 1;
return -1;
}

usort($ary,'scoreAsc');

The function will receive, for example, $ary[0] as $a and $ary[1] as $b.

Right on, cameraman. And here are some more examples and explanations, including one that shows how to parse a text file and add some extra comparison code to the function:

[webmasterworld.com...]
[webmasterworld.com...]
[webmasterworld.com...]
[webmasterworld.com...]
