You can do it using foreach loop.

          $arrayVal = array(1,2,3,1,2,3,1,2,3,4,4,5,6,4,5,6,88);
          $set_array = array();
          foreach ($array as $value) {
            $set_array[$value]++;
          }
           print_r($set_array);

Output :-

  Array( [1] => 3
             [2] => 3
             [3] => 3
             [4] => 3
             [5] => 2
             [6] => 2
             [88] => 1
            )
