方法一：

//直接用頭部資訊輸出excel格式檔案，內容以表格形式展示。

$filename='orderexcel';
    header("Content-type: application/vnd.ms-excel; charset=gbk");
    header("Content-Disposition: attachment; filename=$filename.xls");
//$list為資料庫查詢結果，既二維陣列。利用迴圈出表格，直接輸出，既線上生成execl檔案
 foreach($list as $key => $val)
    {
        $data .= "<table border='1'>";
        $data .= "<tr><td colspan='2'>訂單號：".$val['order_sn']."</td><td>使用者名稱：".$val['user_name']."</td><td colspan='2'>收貨人：".$val['consignee']."</td><td colspan='2'>聯絡電話：".$val['tel']."</td></tr>";
        $data .= "<tr><td colspan='5'>送貨地址：".$val['address']."</td><td colspan='2'>下單時間：".$val['add_time']."</td></tr>";
        $data .= "<tr bgcolor='#999999'><th>序號</th><th>貨號</th><th>商品名稱</th><th>市場價</th><th>本店價</th><th>購買數量</th><th>小計</th></tr>";
        $data .= "<tr><th>1</th><th>".$val['goods_sn']."</th><th>".$val['goods_name']."</th><th>".$val['market_price']."</th><th>".$val['goods_price']."</th><th>".$val['goods_number']."</th><th>".$val['money']."</th></tr>";
        $data .= "</table>";
        $data .= "<br>";
}
$data.='</table>';
    if (EC_CHARSET != 'gbk')
    {
        echo yzy_iconv(EC_CHARSET, 'gbk', $data) . "\t";
    }
    else
    {
        echo $data. "\t";
    }
 

方法二：

//利用excel匯出外掛PHPExcel
 // 引入phpexcel核心類檔案
    require_once ROOT_PATH . '/includes/phpexcel/Classes/PHPExcel.php';
    // 例項化excel類
    $objPHPExcel = new PHPExcel();
    // 操作第一個工作表
    $objPHPExcel->setActiveSheetIndex(0);
    // 設定sheet名
    $objPHPExcel->getActiveSheet()->setTitle('xx列表');

    // 設定表格寬度
    $objPHPExcel->getActiveSheet()->getColumnDimension('A')->setWidth(10);
    $objPHPExcel->getActiveSheet()->getColumnDimension('B')->setWidth(20);
    $objPHPExcel->getActiveSheet()->getColumnDimension('C')->setWidth(15);
    $objPHPExcel->getActiveSheet()->getColumnDimension('D')->setWidth(50);
    $objPHPExcel->getActiveSheet()->getColumnDimension('E')->setWidth(20);
    $objPHPExcel->getActiveSheet()->getColumnDimension('F')->setWidth(5);
    $objPHPExcel->getActiveSheet()->getColumnDimension('G')->setWidth(20);


    // 列名錶頭文字加粗
    $objPHPExcel->getActiveSheet()->getStyle('A1:J1')->getFont()->setBold(true);
    // 列表頭文字居中
    $objPHPExcel->getActiveSheet()->getStyle('A1:J1')->getAlignment()
        ->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);

    // 列名賦值
    $objPHPExcel->getActiveSheet()->setCellValue('A1', '編號');
    $objPHPExcel->getActiveSheet()->setCellValue('B1', '姓名');
    $objPHPExcel->getActiveSheet()->setCellValue('C1', '電話');
    $objPHPExcel->getActiveSheet()->setCellValue('D1', '擅長');
    $objPHPExcel->getActiveSheet()->setCellValue('E1', '建立日期');
    $objPHPExcel->getActiveSheet()->setCellValue('F1', '稽核');
    $objPHPExcel->getActiveSheet()->setCellValue('G1', '稽核時間');

    // 資料起始行
    $row_num = 2;
    // 向每行單元格插入資料
    foreach($res as $value)
    {
        // 設定所有垂直居中
        $objPHPExcel->getActiveSheet()->getStyle('A' . $row_num . ':' . 'J' . $row_num)->getAlignment()
            ->setVertical(PHPExcel_Style_Alignment::VERTICAL_CENTER);
        // 設定價格為數字格式
        $objPHPExcel->getActiveSheet()->getStyle('D' . $row_num)->getNumberFormat()
            ->setFormatCode(PHPExcel_Style_NumberFormat::FORMAT_NUMBER_00);
        // 居中
        $objPHPExcel->getActiveSheet()->getStyle('E' . $row_num . ':' . 'H' . $row_num)->getAlignment()
            ->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);

        // 設定單元格數值
        $objPHPExcel->getActiveSheet()->setCellValue('A' . $row_num, $value['id']);
        $objPHPExcel->getActiveSheet()->setCellValue('B' . $row_num, $value['teacher_name']);
        $objPHPExcel->getActiveSheet()->setCellValue('C' . $row_num, $value['teacher_mobile']);
        $objPHPExcel->getActiveSheet()->setCellValue('D' . $row_num, $value['teacher_desc']);
        $objPHPExcel->getActiveSheet()->setCellValue('E' . $row_num, date('Y-m-d h:i:s',$value['createtime']));
        $objPHPExcel->getActiveSheet()->setCellValue('F' . $row_num, $value['state'] ? '√' : '×');
        $objPHPExcel->getActiveSheet()->setCellValue('G' . $row_num, date('Y-m-d h:i:s',$value['statetime']));
        $row_num++;
    }

    $outputFileName = 'teacher_' . time() . '.xls';
    $xlsWriter = new PHPExcel_Writer_Excel5($objPHPExcel);
    header("Content-Type: application/force-download");
    header("Content-Type: application/octet-stream");
    header("Content-Type: application/download");
    header('Content-Disposition:inline;filename="' . $outputFileName . '"');
    header("Content-Transfer-Encoding: binary");
    header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
    header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
    header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
    header("Pragma: no-cache");
    $xlsWriter->save("php://output");
    echo file_get_contents($outputFileName);
