I have this array
Array (
[146] => Post Object (
[ID] => 5664
[post_author] => 8
[post_date] => 2016-04-10 16:21:55
[post_content] =>
)
[145] => Post Object (
[ID] => 5638
[post_author] => 7
[post_date] => 2016-03-17 12:23:00
[post_content] =>
)
)
I want to order my array by the numbers before "=> Post Object".
i.e. I want that the sub-array 145 appear before 146.
You can use ksort function.
ksort($array);
For others behaviour read the related documentation at http://php.net/manual/en/array.sorting.php
