As some people have mentioned before sorting a multidimentional array can be a bit tricky. it took me quite a while to get it going but it works as a charm:
<?php
function sortmulti ($array, $index, $order, $natsort=FALSE, $case_sensitive=FALSE) {
if(is_array($array) && count($array)>0) {
foreach(array_keys($array) as $key)
$temp[$key]=$array[$key][$index];
if(!$natsort) {
if ($order=='asc')
asort($temp);
else
arsort($temp);
}
else
{
if ($case_sensitive===true)
natsort($temp);
else
natcasesort($temp);
if($order!='asc')
$temp=array_reverse($temp,TRUE);
}
foreach(array_keys($temp) as $key)
if (is_numeric($key))
$sorted[]=$array[$key];
else
$sorted[$key]=$array[$key];
return $sorted;
}
return $sorted;
}
?>
