You can use the classic foreach to group the array into a multidimensional array. Use array_values to convert the multidimensional array to simple array.

$result = array();
foreach( $arr as $val ) {
    if ( !isset( $result[$val->referal_user_id] ) ) $result[$val->referal_user_id] = $val;
}

$result = array_values( $result );

echo "<pre>";
print_r( $result );
echo "</pre>";

This will result to:

Array
(
    [0] => stdClass Object
        (
            [id] => 23
            [user_id] => 21
            [referal_user_id] => 16
            [membership_name] => 4
            [points] => 100
            [used_code] => CEMJ916
            [earned_date] => 2018-06-11 06:34:00
        )

    [1] => stdClass Object
        (
            [id] => 25
            [user_id] => 16
            [referal_user_id] => 1
            [membership_name] => 2
            [points] => 200
            [used_code] => CEMJ916
            [earned_date] => 2018-06-06 08:36:46
        )

just create a blank array and store the referal_user_id in it if that id dosen't exist in array you skip else print.

e.g.

$unique_array = array();
$unique_referal_ids = array();
foreach($array as $value)
{
  if(!in_array($value->referal_user_id, $unique_referal_ids))
  {
     array_push($unique_array, $value);
     array_push($unique_referal_ids, $value->referal_user_id);  
  }
}

print_r($unique_array);

and you'll get your desired result.

You can use in_array function to find the duplicate so in that function will skip duplicate and you will get your desired result.
