In questo tutorial PHP imparerete come ordinare un’array da una chiave specifica mantenendo l’associazione dell’indice.

 
function array_sort($array, $on, $order=SORT_ASC) {
$new_array = array();
$sortable_array = array();
if (count($array) > 0) {
foreach ($array as $k => $v) {
if (is_array($v)) {
foreach ($v as $k2 => $v2) {
if ($k2 == $on) {
$sortable_array[$k] = $v2;
}
}
} else {
$sortable_array[$k] = $v;
}
}
 
switch ($order) {
case SORT_ASC:
asort($sortable_array);
break;
case SORT_DESC:
arsort($sortable_array);
break;
}
 
foreach ($sortable_array as $k => $v) {
$new_array[$k] = $array[$k];
}
}
 
return $new_array;
}
