Advanced sort array by second index function, which produces ascending (default) or descending output and uses optionally natural case insensitive sorting (which can be optionally case sensitive as well).
Only the first two arguments are required.
<?php
function sabsi ($array, $index, $order='asc', $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) ($order=='asc')? asort($temp) : arsort($temp);
else {
($case_sensitive)? natsort($temp) : natcasesort($temp);
if($order!='asc') $temp=array_reverse($temp,TRUE);
}
foreach(array_keys($temp) as $key) (is_numeric($key))? $sorted[]=$array[$key] : $sorted[$key]=$array[$key];
return $sorted;
}
return $array;
}
?>
