php - Code igniter Outputting data from cache -

i have following functions in controller :

public function cached_icd10() {         /* information database , cache information         */         $this->load->driver('cache', array('adapter' => 'file'));          $cacheid = "icd10";         if (!$cache_data = $this->cache->get($cacheid)) {             //ge information  database              $data['icd10_codes'] = $this->icd_10_codes();              // save cache 5 minutes             $this->cache->save($cacheid, $data['icd10_codes'], 300);             $cache_data = $data['icd10_codes'];         }         return $cache_data;      }      public function form() {         //fetch icd10 codes cache file icd10          $cache_data = $this->cached_icd10();           $this->load->view('form', $cache_data);     } 

the first function caches information database , second 1 passes view called form. when try output information view , fails throwing error : message: undefined variable: cache_data while when try controller echoes well. using code below :

 <?php     foreach ($cache_data $value) {         echo 'out put per line ....:    ' . $value['icd_description'] . ' ,  id .... ' . $value['id'] . '<br>';     }     ?> 

how can display information controller view ?

you can pass cache data view using array

public function form() {      //fetch icd10 codes cache file icd10         $cache_data = $this->cached_icd10();         $data['cache_data']=$cache_data;// create , pass data array         $this->load->view('form', $data);     } 

you can cache data in view with

foreach ($cache_data $value) {        // code here     }
