    Hint: [`array_unique()`](http://php.net/manual/en/function.array-unique.php) and [`sort()`](http://php.net/manual/en/function.sort.php) – jensgram Sep 11 '14 at 07:45
  • _number increase sort_ -- what does that mean? Do you mean _sort numbers in increasing order_? – Barmar Sep 11 '14 at 07:48

Your friends are: array_unique() and sort()

With these functions you can create the distinct list and sort it:

$a = {2,3,2,1,3,2,0,3,2,0,11,7,9,2}
$b = array_unique($a, SORT_NUMERIC)
sort($b, SORT_NUMERIC)

You have to filter/sort by distinct number values and order ascending..

Unique values: Select only unique array values from this array

Order values: http://www.w3schools.com/php/php_arrays_sort.asp

You need to get all unique values and then sort them. array_unique() removes all duplicate values. sort() sorts your values from low to high.

$B = array_unique($A);
sort($B);

  • `sort` returns a boolean, not a new array. Its argument has to be a variable, not an expression, because it takes a reference. – Barmar Sep 11 '14 at 07:49
  • @Barmar You're absolutely right. I posted my answer a bit to fast. Edited answer. – TeeDeJee Sep 11 '14 at 07:50

//remove duplicate values from array using array_unique
$unique_array = array_unique($a);
//sort the resulting array
sort($unique_array);
//dump it to verify
var_dump($unique_array);
