excel資料導出，PHPExcel資料導出

1.下載下傳PHPExcel

2.放到我們項目的Application/Common下面

放入上面連個檔案即可

3.引入PHPExcel和導出資料

public function index(){
	$data=$model->where('status','1')->select();
	$this->downs($data);
}
public function downs($data){
        require_once 'Application/Common/PHPExcel.php';
        // 檔案名和檔案類型
        $fileName = "提現申請";
        $fileType = "xlsx";

        // 模拟擷取資料

        $obj = new \PHPExcel();
        // var_dump($data);die;
        // 以下内容是excel檔案的資訊描述資訊
        $obj->getProperties()->setCreator('wqb'); //設定建立者
        $obj->getProperties()->setLastModifiedBy('reps'); //設定修改者
        $obj->getProperties()->setTitle('title'); //設定标題
        $obj->getProperties()->setSubject('them'); //設定主題
        $obj->getProperties()->setDescription('desc'); //設定描述
        $obj->getProperties()->setKeywords('keys');//設定關鍵詞
        $obj->getProperties()->setCategory('type');//設定類型

        // 設定目前sheet
        $obj->setActiveSheetIndex(0);

        // 設定目前sheet的名稱
        $obj->getActiveSheet()->setTitle('student');

        // 列标
        $list = ['A', 'B', 'C'];

        // 填充第一行資料
        $obj->getActiveSheet()
            ->setCellValue($list[0] . '1', 'id')

            ->setCellValue($list[2] . '1', '電話')
        ;

        // 填充第n(n>=2, n∈N*)行資料
        $length = count($data);
//        for ($i = 0; $i < $length; $i++) {
            foreach ($data as $key=>$value){
                $obj->getActiveSheet()->setCellValue($list[0] . ($key + 2), $value['id'], \PHPExcel_Cell_DataType::TYPE_STRING);//将其設定為文本格式
                $obj->getActiveSheet()->setCellValue($list[1] . ($key + 2), $value['bank_name']);//将其設定為文本格式
                $obj->getActiveSheet()->setCellValue($list[2] . ($key + 2), $value['phone']);//将其設定為文本格式
            }

//        }

        // 設定加粗和左對齊
        foreach ($list as $col) {
            // 設定第一行加粗
            $obj->getActiveSheet()->getStyle($col . '1')->getFont()->setBold(true);
            // 設定第1-n行，左對齊
            for ($i = 1; $i <= $length + 1; $i++) {
                $obj->getActiveSheet()->getStyle($col . $i)->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_LEFT);
            }
        }

        // 設定列寬
        $obj->getActiveSheet()->getColumnDimension('A')->setWidth(20);
        $obj->getActiveSheet()->getColumnDimension('B')->setWidth(20);
        $obj->getActiveSheet()->getColumnDimension('C')->setWidth(15);
        // var_dump($obj);
        // 導出
        ob_clean();
