php mysql how to get the value inside an array

Question

array(1) {
  [0] => array(2) {
    ["list_length"] => string(2) "10" 
    ["id"] => array(4) {
      [0] => string(1) "1"
      [1]=> string(2) "10" 
      [2]=> string(1) "3"
      [3]=> string(2) "13"
    }
  }
}

codeigniter

How can I get the values 1,10,3,13 inside

["id"]=> array(4) {
  [0]=> string(1) "1"
  [1]=> string(2) "10"
  [2]=> string(1) "3"
  [3]=> string(2) "13"
}

I tried :

public function recieve($data){
    //var_dump($data);
    $ids = $data;
    var_dump($ids);
    $this->db->set('recieve', '1');
    $this->db->where('no', $ids);
    $this->db->update('trainee')`
 }

why you are using <recieve> method , its not clear, pls specify — Pradeep

What have you tried so far? The given array has clear keys, so why not use them? — Nico Haase

Hope this will help you :

Working demo : https://eval.in/1009067

$arr = array(array("list_length" => "10" ,"id" => array("1", "10" , "3" , "13")));
if (! empty($arr[0]['id']))
{
   $data = $arr[0]['id'];
}
print_r($data);

Output :

Array
(
    [0] => 1
    [1] => 10
    [2] => 3
    [3] => 13
)

In your recieve method use like this :

$arr = array(array("list_length" => "10" ,"id" => array("1", "10" , "3" , "13")));

if (! empty($arr[0]['id']))
{
   $data = $arr[0]['id'];
}

/*pass this $data to your method like this :*/

public function recieve($data)
{
    /*if $data is return the array just like above in question 
      get all ids like this 
      $ids = $data[0]['id'];
    */
    $ids = $data;
    //var_dump($ids);
    $this->db->set('recieve', '1');
    $this->db->where_in('no', $ids);
    $this->db->update('trainee')`
 }
