Sorting a little more complex array than just the normal PHP array

$clients= new Array();

$clients[0]['id'] = 1;
$clients[0]['name'] = "Dave";
$clients[1]['id'] = 2;
$clients[1]['name'] = "Alex";
$clients[2]['id'] = 3;
$clients[2]['name'] = "Chris";
$clients[3]['id'] = 4;
$clients[3]['name'] = "Cindy";
$clients[4]['id'] = 4;
$clients[4]['name'] = "Albert";

function cmp($a, $b){
  return strcmp($a['name'], $b['name']);
}
usort($clients, "cmp");

To sort a normal array you can use the PHP function sort.

To invert the search (descending order) you merely have to invert the two variable in the "cmp" function like this:

function cmp($a, $b){
  return strcmp($b['name'], $a['name']);
}
