[Resolved] sort multi-dimensional array

[dewen]

hi, I'm trying to sort this array by "id", any help is appreciated

$arr_test['984561'] = array( "id" =>17, "subid" => "1", "type_id" =>"3");
$arr_test['984522'] = array( "id" =>3, "subid" => "1", "type_id" =>"5");
$arr_test['984363'] = array( "id" =>1, "subid" => "2", "type_id" =>"5");
$arr_test['982564'] = array( "id" =>14, "subid" => "3", "type_id" =>"1");
$arr_test['184565'] = array( "id" =>8, "subid" => "2", "type_id" =>"3");
$arr_test['454566'] = array( "id" =>2, "subid" => "1", "type_id" =>"4");
$arr_test['984567'] = array( "id" =>4, "subid" => "1", "type_id" =>"6");
$arr_test['984568'] = array( "id" =>7, "subid" => "3", "type_id" =>"3");
$arr_test['984569'] = array( "id" =>9, "subid" => "4", "type_id" =>"3");

tried already, but didn't figure it out since this array is not fixed size.

shouldnt matter if you use something like example 3 on that page which shows it working with a result from a db which technically could not be a fixed size.

Catharsis, you are right. I was kept blind by an old manual

except my num keys lost after sort 🙁
