[RESOLVED] sort array help please

[clairence]

I know this has probably been covered over and over again.
I've read the manual on sort,usort, arsort, etc., and read various threads here.

But I can't seem to locate a solution to my dilemma. Or maybe I've seen it but I just don't "get" it.

I have an array of 32 arrays:

$game[1]=array($gameID,$team,$points)
$game[2]=array($gameID,$team,$points)
etc

I want to sort $game by $points.

how would I go about doing that?

Thanks.

function mySort($a, $b)
{
   return($a - $b);
}
usort($game, 'mySort');

To reverse the sort order, simply exchange the $a and $b in the return statement of the mySort() function.

Here's how you'd sort by points in descending order:

usort($game, create_function('$a,$b', 'return ($a[2] < $b[2] ? 1 : -1);'));

Brad and nogdog, thanks so much for your helpful replies!

I had been using a function similar to the ones you shared, but was getting junk outputs so figured I just didn't understand the function.

In reality, I needed to be focused on the first half of GIGO. Once I fed the proper data into the formula it worked as desired.

Much thanks.
