Here, I m using PHPexcel library to reading the file. My excel File look like
Controller
class Home extends CI_Controller {
    public function index() {
        $this->load->library('excel');
        $reader = PHPExcel_IOFactory::createReader('Excel2007');
        $reader->setReadDataOnly(true);
        $file = isset($_FILES["uploadexcel"]['tmp_name']) ? $_FILES["uploadexcel"]['tmp_name'] : '';
        $excel = $reader->load($file);
        foreach ($excel->getWorksheetIterator() as $worksheet) {
            $worksheets = $worksheet->toArray();
        }
        echo '<pre>';print_r($worksheets);
    }
}
when I am uploading excel file my array like:
 Array
 (
  [0] => Array
    (
        [0] => url
        [1] => category_1
        [2] => category_2
        [3] => language
        [4] => f_n
        [5] => publishers
        [6] => cost
        [7] => cost_currency
        [8] => processing_time
        [9] => example
        [10] => note
    )
    [1] => Array
    (
        [0] => gettingaway.com
        [1] => 10
        [2] => 14
        [3] => GA
        [4] => nofollow
        [5] => 2
        [6] => 1245
        [7] => 
        [8] => 12
        [9] => testing
        [10] => Testing Value
    )
 )
But, I want the array like :
Array
   (
    [0] => Array
    (
        [url] => gettingaway.com
        [category_1] => 10
        [category_2] => 14
        [language] => GA
        [f_n] => nofollow
        [publishers] => Cust Angel
        [cost] => 12
        [cost_currency] => USD
        [processing_time] => 12
        [example] => example
        [note] => note
    )   
    [1] => Array
    (
        [url] => thebusbench.com
        [category_1] => 5
        [category_2] => 13
        [language] => GA
        [f_n] => nofollow
        [publishers] => Cust Angel
        [cost] => 12
        [cost_currency] => USD
        [processing_time] => 6
        [example] => example
        [note] => note
    )   
    [2] => Array
    (
        [url] => travelintelligence.net
        [category_1] => 6
        [category_2] => 11
        [language] => GA
        [f_n] => nofollow
        [publishers] => Cust Angel
        [cost] => 12
        [cost_currency] => USD
        [processing_time] => 2
        [example] => example
        [note] => note
    )      
 )
In above array, my publisher key value is 2. i.e. the Id of publisher into my database. I want this related id publisher name into array. In my database id 2 related publisher name is Cust Angel.
