using array_unique in php codeigniter the returing only one value

Question

If using array_unique in php codeigniter, it returns only on value. please give an guideline to solve the issue, I'm new to programming. I'm code is below.

Controllers    
function get_rck_detail()
{
$partnumber = $this->input->post('part_number');
$subbrand = $this->input->post('subbrand');
$part = $this->suggest->get_part_code($partnumber);
$rack_list = $this->suggest->get_rack_details($part,$subbrand);
echo '<option>--Location--</option>';
foreach(array_unique($rack_list) as $rack)
{

echo '<option value="'.$rack['rs_loc'].'">'.$rack['rack_name'].'</option>';
}
}

models

function get_rack_details($part,$subbrand)
 {
$this->db->select('*');
$this->db->from('rack_spares');
$this->db->join('rack_name','rack_spares.rs_loc = rack_name.rn_id');
$this->db->where('rs_product_code',$part);
$this->db->where('rs_sub',$subbrand);
$query = $this->db->get();
return $query->result_array();
}

$rack_list is not single dimensional array. It's two dimensional array. — Kumar V

array_unique compares elements as strings. All arrays are cast to the string "Array" and are therefore all equal in the eyes of array_unique.

Try passing SORT_REGULAR as the second parameter, this should compare the arrays as arrays, ie. returning them as equal if they have the same key/value pairs in the same order. You may need to ksort your arrays first.

Are your arrays, in fact, unique? Or just the name?

user3265980 Over a year ago

it's not just a name, it's an array value of total row in database

What I'm asking is, are the rows completely identical?

user3265980 Over a year ago

yes sir, actually the output of array like [0] => Array ([rs_id] => 21[rs_product_code] => PRD001[rs_sub_id] => 3[rs_sub] => BRUCE[rs_loc] => 1[rs_ser] => AA[rs_num] => 411[rck_quan] => 0[rs_created_date] => 2014-02-10 13:04:09[rn_id] => 1 [rack_name] => GODOWNS )

In your Controller,

$this->load->helper('form');
$rack_list = $this->suggest->get_rack_details($part,$subbrand);
$res = array();
foreach($rack_list as $r)
   $res[$r["rs_loc"]] = $r["rack_name"]; // removes duplicates as we are assigning for keys   
$res[""] = "---Location---";
echo form_dropdown("location",$res); // this will produce <select><option></option>...</select>

In your view file, Remove existing <select> as controller generating options with select

As per your expectation, to get only options run below loop in controller instead of form_dropdown

$ret_content = "";
foreach($res as $k => $v)
  $ret_content .="<option value='".$k."'>".$v."</option>";

echo $ret_content;
