Suppose in image its 3 worksheets in one excel. HOw can i access to second and third worksheet?? Please give me some help. Thanks

Try using PHPExcel on reading your excel file.

function read_excel(){
        //Load library plugin
        $this->load->library('excel');

        /** Error reporting */
        error_reporting(E_ALL);
        ini_set('display_errors', TRUE);
        ini_set('display_startup_errors', TRUE);
        define('EOL',(PHP_SAPI == 'cli') ? PHP_EOL : '<br />');

        //Open excel file
        $objPHPExcel = PHPExcel_IOFactory::load(FCPATH."file.xls");

        // go through your worksheet if you have multiple worksheet inside the excel file
        foreach ($objPHPExcel->getWorksheetIterator() as $worksheet) {
            //read each row of the worksheet
            foreach ($worksheet->getRowIterator() as $row) {
                //get cells
                $cellIterator = $row->getCellIterator();
                $cellIterator->setIterateOnlyExistingCells(false);
                foreach ($cellIterator as $cell) {
                    //get cell values
                    $cell->getCalculatedValue();
                }
            }
        }
}

tweak this code in your need.

When i am Exploring PHPExcel.php i get the solution that i am going to share with other too.

 $target_file   = $path . basename($_FILES["files"]["name"]);// storing the excel file to folder
 $file_id       = basename($_FILES["files"]["name"]);
 $FileType  = pathinfo($target_file, PATHINFO_EXTENSION);

 move_uploaded_file($_FILES["files"]["tmp_name"], $target_file);

 $load_file = $target_file;

 $update4       = array('file_id' => $file_id,);

 $this -> load -> library('Excel');

 $objPHPExcel   = PHPExcel_IOFactory::load($load_file);

 $sheet_count   = $objPHPExcel->getSheetCount();// this function give me worksheets count.
 for($s=0; $s<$sheet_count; $s++){// using for lop to get specific worksheet data
    $cell_collection= $objPHPExcel->getSheet($s)->getCellCollection();

    foreach ($cell_collection as $cell) {
        $column     = $objPHPExcel -> getSheet() -> getCell($cell) -> getColumn();
        $row        = $objPHPExcel -> getSheet() -> getCell($cell) -> getRow();
        $data_value = $objPHPExcel -> getSheet() -> getCell($cell) -> getValue();

        if ($row == 1) {// if you have header in your excel or want to store then store in header.
            $header[$s][$row][$column] = $data_value;
        } else {// i get my meaningful data from here :)
            $arr_data[$s][$row][$column] = $data_value;
        }
    }
}// end of for loop for getting the work sheet
