CI里数组转换问题
查询数组 
$str2="from crm_ltsz_customer_info_def";

if($_POST["EmployeeId"]!="" && $_POST["EmployeeId"]!=null)
{
$str3=" bl_salesman_id=".$_POST["EmployeeId"]." and";
};

$array1[0]= $this->db->query('select count(customer_id) as `count` '.$str2.' where '.$str3." year(create_time)=".$_POST["CreateTime"]." and month(create_time)='01'");
  $array1[1]= $this->db->query('select count(customer_id) as `count` '.$str2.' where '.$str3." year(create_time)=".$_POST["CreateTime"]." and month(create_time)='02'");
  $array1[2]= $this->db->query('select count(customer_id) as `count` '.$str2.' where '.$str3." year(create_time)=".$_POST["CreateTime"]." and month(create_time)='03'");
  $array1[3]= $this->db->query('select count(customer_id) as `count` '.$str2.' where '.$str3." year(create_time)=".$_POST["CreateTime"]." and month(create_time)='04'");
  $array1[4]= $this->db->query('select count(customer_id) as `count` '.$str2.' where '.$str3." year(create_time)=".$_POST["CreateTime"]." and month(create_time)='05'");

  $result = array();
  foreach ( $array1 as $v ) {
$result[] = $v->row_array();
  }
  print_r($result);
  exit();

出的结果是

  )
