Hello !
I have an example array:
$a = array(
5 => 35,
16 => 22,
7 => 22,
3 => 22,
11 => 22,
9 => 27,
);
and I want to sort it by values and remember its keys. Result that I expected was:
$a = array(
16 => 22,
7 => 22,
3 => 22,
11 => 22,
9 => 27,
5 => 35,
);
So my first thought was: asort
!
Ok, I did
asort($a);
But no - it didn't just move 5 => 35
to the end of the array.
It changed my array to:
$a = array(
11 => 22,
3 => 22,
7 => 22,
16 => 22,
9 => 27,
5 => 35
);
You see ? Keys with the same value are reverse sorted. Why ?
