如何从数组中提取数据 - PHP Codeigniter

How can I extract the field: chat_id from this array? I'm trying to put the chat_id in the id of a button in html.

Array
(
    [0] => stdClass Object
        (
            [id] => 2
            [first_name] => Armani
            [last_name] => Dee
            [contact_number] => 123456
            [email_address] => hello@gmail.com
            [home_address] => 
            [username] => armani
            [password] => 12345
            [status] => 0
            [email_confirmed] => 0
            [chat_id] => 14
            [admin_id] => 0
            [customer_id] => 2
            [partner_id] => 0
            [timestamp] => 2018-06-15 22:38:24
            [chat_exists] => 1
            [reply_id] => 208
            [message] => Hello 
            [timestamp_reply] => 2018-06-16 14:02:44
            [chat_status] => 0
        )

)

I got my output from my model:

public function chat_customer($enum) 
{
    $this->db->select('*');
    $this->db->from('customer');
    $this->db->order_by('timestamp','desc');
    $this->db->where('customer.id',$enum);
    $this->db->join('chat','chat.customer_id = customer.id','left');
    $this->db->join('chat_reply', 'chat_reply.chat_id = chat.chat_id', 'left');
    $query = $this->db->get();
    return $query->result();
}

Then I retrieved it in my controller like this:

 $customer_id = $this->input->get('message');
 $this->load->model('Crud_model');
 $data = $this->Crud_model->chat_customer($customer_id);
 echo print_r($data);

I'm trying to print the 14 on the chat_id. Thank you for your help!
