Sort Array by Year Gives Wrong Order

[jarvis]

Hi,

I have a loop which creates an array:

$productions[] = array( 'url'=>get_the_permalink(), 'year'=>$production_year->name, 'title'=>get_the_title() );

When I output the results, the year is in the wrong order:

2019
2018
2017
2016
2015
2014
2020

What I can't work out is how to order 2014 - 2020

I tried ksort(array, SORT_STRING) and ksort(array, SORT_NUMERIC)

I also tried natsort 

But still have the same issue - am I missing something?

Thanks

Sorted it with

usort($productions, function($a1, $a2) {
   $v1 = strtotime($a1['year']);
   $v2 = strtotime($a2['year']);
   return $v2 - $v1; // $v2 - $v1 to reverse direction
});

FYI, as of php7, you could write it as

usort($productions, function($a1, $a2) {
   return $a2['year'] <=> $a1['year'];
});
