　　public function export_data($data = array())

　　{

　　# code...

　　include_once(APP_PATH.'Tools/PHPExcel/Classes/PHPExcel/Writer/IWriter.php') ;

　　include_once(APP_PATH.'Tools/PHPExcel/Classes/PHPExcel/Writer/Excel5.php') ;

　　include_once(APP_PATH.'Tools/PHPExcel/Classes/PHPExcel/IOFactory.php') ;

　　$obj_phpexcel = new PHPExcel();

　　$obj_phpexcel->getActiveSheet()->setCellValue('a1','Key');

　　$obj_phpexcel->getActiveSheet()->setCellValue('b1','Value');

　　if($data){

　　$i =2;

　　foreach ($data as $key => $value) {

　　# code...

　　$obj_phpexcel->getActiveSheet()->setCellValue('a'.$i,$value);

　　$i++;

　　}

　　}   

　　$obj_Writer = PHPExcel_IOFactory::createWriter($obj_phpexcel,'Excel5');

　　$filename = "outexcel.xls";

　　header("Content-Type: application/force-download");
