So I am looking to sort the multi dimensional array below by "fk_page_id" ascending. Does anyone have any pointers. I think usort() is where I have to look but it seems like I cant find anyone with my specific array structure.
Array
(
[0] => Array
(
[title] => subpage of subpage!
[id] => 5
[long_title] =>
[fk_page_id] => 4
)
[1] => Array
(
[title] => about us subpage
[id] => 4
[long_title] =>
[fk_page_id] => 2
)
[2] => Array
(
[title] => about us
[id] => 2
[long_title] =>
[fk_page_id] => 1
)
)
if you're using PHP 5.3+:
define(ASC,1);
define(DESC,-1);
function colsort($array,$col,$order=ASC) {
usort(
$array,
function($a,$b) use($col,$order) {
return strcmp($a[$col],$b[$col])*$order;
}
);
return $array;
}
colsort($x,'fk_page_id');
