Answer 2

$q = [1,3,6,2,8,9,4];  //let's say any array

for($i = 0; $i<=count($q)-1;$i++){
  for($j =0; $j<count($q)-1;$j++){
     if($q[$j] < $q[$j+1]){         //for ASC or DESC just switch '>' or '<'
          $var = $q[$j+1];
          $q[$j+1] = $q[$j];
          $q[$j]=$var;              
     }
   }
}
print_r($q);  //This is sorted array'
