[codeigniter] Showing all session data at once?

For print session data you do not need to use print_r() function every time .

If you use it then it will be non-readable format.Data will be looks very dirty.

But if you use my function all you have to do is to use p()-Funtion and pass data into it. //create new file into application/cms_helper.php and load helper cms into //autoload or on controller

/*Copy Code for p function from here and paste into cms_helper.php in application/helpers folder */

   //@parram $data-array,$d-if true then die by default it is false
   //@author Your name

    function p($data,$d = false){

          echo "<pre>"; 
             print_r($data);
          echo "</pre>"; 

        if($d == TRUE){
             die();
          } 
      }

Just remember to load cms_helper into your project or controller using $this->load->helper('cms'); use bellow code into your controller or model it will works just GREAT.

 p($this->session->all_userdata()); // it will apply pre to your sesison data and other array as  well
