messing around with an array - part 2

[Anon]

I have an array as follows:

    $crazy_array = ( 
          0 => array ("number" => "0", "inf" => "1"),
          1 => array ("number" => "1", "inf" => "2"),
          2 => array ("number" => "2", "inf" => "3"),
          3 => array ("number" => "3", "inf" => "1"),
          4 => array ("number" => "4", "inf" => "14"),
          5 => array ("number" => "5", "inf" => "11"),
          6 => array ("number" => "6", "inf" => "10"),

I need to order it by "INF". Is this possible ? It would be ordened kinda like as follows:

     0 3 1 2 6 5 4

I tried with sort but it didn't seam to produze the result I want.

you need to use

usort($myarray, myfun);

where myfun() takes two elements of the array and returns -1 or 1 depending on how you would order them.

e.g.

function myfun($a, $b) {
if ($a['inf'] > $b['inf']) {
return -1;
else {
return 1;
}
}

hope this helps.
