Sort array by keys of another array.
- by marbrun
Hello
There are 2 arrays, both with the same length and with the same keys:
$a1 = [1=>2000,65=>1354,103=>1787];
$a2 = [1=>'hello',65=>'hi',103=>'goodevening'];
asort($a1);
The keys of a1 and a2 are id's from a database.
a1 gets sorted by value. Once sorted, how can we use the same sorting order in a2?
Thanks!
