mysql - How to get all orders last 30 days with date range using codeigniter PHP? -

-

here table , need fetch data mysql database display 30 days counting total number of orders per day. , there date range.

example 1: current date aug 08, 2016. need display last 30 days aug 08, 2016.

order table  id | customer_id | num_of_order |date ---+-------------+--------------+--------       1  |    10001    |      1       | 2016-08-08 07:23:50  2  |    10002    |      4       | 2016-08-07 11:33:50   3  |    10003    |      2       | 2016-08-06 15:44:50 //same day  4  |    10001    |      5       | 2016-08-06 20:50:50 //same day 5  |    10004    |      3       | 2016-08-04 11:17:50

now expected output display:

array (     [0] => array (         [date] => 2016-08-08         [total_orders] => 1     )     [1] => array (         [date] => 2016-08-07         [total_orders] => 4     )     [2] => array (         [date] => 2016-08-06         [total_orders] => 7     )     [3] => array (         [date] => 2016-08-05         [total_orders] => 0  //no orders still need include in output     )     [4] => array (         [date] => 2016-08-04         [total_orders] => 3     )     //and forth (july 09, 2016)..... )

is there php codeigniter code this?

$this->db->select("date_format(date,'%y-%m-%d') covered_date,count(date(date)) total_order"); $this->db->from('order'); $this->db->where('date > date_sub( "2016-08-08" , interval 30 day )'); $this->db->group_by("date(date)"); $query = $this->db->get(); $result = $query->result_array(); $start_date = date('y-m-d', strtotime('-30 day', strtotime($end_date))); $return = array();  while (strtotime($start_date) <= strtotime($end_date)) {     $return[] = $start_date;     $start_date = date("y-m-d", strtotime("+1 day", strtotime($start_date))); } print_r($return);
