I have a nested array.
[0]
( [0] = 4 [1] = value1)
[1]
( [0] = 2 [1] = value2)
There are a about a hundred or so everything this runs.
The first value (4 or 2) are value indicators for the value (value1 or
value2). Like a ranking of sorts.
These values are ranked in groups from 1 to 20. There could be 30 items
that fall in the ranking of 15 category. There might be only five items
ranked as a 5.
So what I want to do is sort these according to rank. So I want all the
ones at the top and 20's at the bottom. Im not sure how to do this :)
Im looking through the php functions for arrays but Im not sure how to
sort based on the first value of a nested array.

Hi Wade,
I can't see an easy way to do it with php array functions. It looks like you
have to flatten the array.
foreach($array as $this_array)
{
foreach($this_array as $key => $value)
{
$new_array[$value] = $key;
}
}
$result = arsort($new_array, SORT_NUMERIC);
It should also be easier in php v 5.x.x because you can move keys and values as
sets.
