this question looks like it should have a simple answer but google and the php manual are being no help to me, maybe I just don't understand what they are telling me.
I have an array example:
$outcomes_array = array(1,4,2,3,5);
It will always contain just numbers, how do I go about sorting this array so that it is always in descending order?
so output I want:
$outcomes_array[0] = 5
$outcomes_array[1] = 4
$outcomes_array[2] = 3
and so on...
Thanks :)
rsort( $outcomes_array )
Note, it is not
$outcomes_array = rsort( $outcomes_array );
rsort( $outcomes_array );
print_r( $outcomes_array );
rsort is just for a numeric arrayarsort is for an array with keys As the default is SORT_REGULAR - compare items normally (don't change types) So the code should be:
$outcomes_array = array(1,4,2,3,5);
rsort( $outcomes_array, SORT_NUMERIC );//SORT_NUMERIC - compare items numerically
print_r( $outcomes_array );
$array = [2, 1, 22, 1, 3, 134, 3, 43, 23, 4];
function mi($arr){
$count = count($arr);
for ($j = 0; $j < $count; $j++) {
$min = $arr[0];
for ($i = 0; $i < count($arr); $i++) {
if ($arr[$i] <= $min) {
$min = $arr[$i];
}
}
$ar[] = $min;
for ($i = 0; $i < count($arr); $i++) {
if ($arr[$i] == $min) {
unset ($arr[$i]);
$arr = array_values($arr);
break;
}
}
}
return $ar;
}
print_r(mi($array));
rsort($outcomes_array);.
