如何在codeigniter中获取请求数据

I am new to codeigniter.

I am trying to print the requested data of form .

I want the bunch of data , but i am unable to fetch it.

Here i am getting single data .I want the whole array of data.

I have tried this below codes .

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Ticket extends CI_Controller {

    public function insert_ticket()
    {   


    echo $title = $this->input->post("title");//getting single data
        print_r($this->input->post);exit;//This one is not working.
    }
}

Thank you.Any suggestion?

$this->input->post this is wrong rather you may try as following because post() is a method not properties

print_r($this->input->post());return;

Try this will may help you

 print_r($this->input->post());
 die(); 

You did a mistake in your code you missing function parentheses post()
code should be like this

print_r($this->input->post());
