Thinkphp 3.2.2 利用phpexcel完成excel导出功能

首先百度搜索phpexcel  包，放到项目的这个目录下

接下来  是controller里的导出代码 

/**

public function expUser(){
   // $p_name = $_POST['order_p_name'];
    $m = M ('order_list');
   // $datas['order_p_name'] = $p_name;
    $data = $m->field('order_id,order_p_name,order_p_price,order_p_username,order_p_tel,order_time')->select();
    foreach ($data as $k => $v)
    {
        $data[$k]['order_time']=$v['order_time']=date('Y-m-d',$v['order_time']);
    }
    //导入PHPExcel类库，因为PHPExcel没有用命名空间，只能inport导入
    import("Org.Util.PHPExcel");
    import("Org.Util.PHPExcel.Writer.Excel5");
    import("Org.Util.PHPExcel.IOFactory.php");
    $filename="test_excel";
    $headArr=array("编号","名称","价格","姓名","电话","日期");
    $this->getExcel($filename,$headArr,$data);
}

private    function getExcel($fileName,$headArr,$data){
    //对数据进行检验
    if(empty($data) || !is_array($data)){
        die("data must be a array");
    }
    //检查文件名
    if(empty($fileName)){
        exit;
    }
    $date = date("Y_m_d",time());
    $fileName .= "_{$date}.xls";
    //创建PHPExcel对象，注意，不能少了
    $objPHPExcel = new PHPExcel();
    $objProps = $objPHPExcel->getProperties();

    //设置表头
    $key = ord("A");
    foreach($headArr as $v){
        $colum = chr($key);
        $objPHPExcel->setActiveSheetIndex(0) ->setCellValue($colum.'1', $v);
        $key += 1;
    }
    $column = 2;
    $objActSheet = $objPHPExcel->getActiveSheet();
    foreach($data as $key => $rows){ //行写入
        $span = ord("A");
        foreach($rows as $keyName=>$value){// 列写入
            $j = chr($span);
            $objActSheet->setCellValue($j.$column, $value);
            $span++;
        }
        $column++;
    }
    $fileName = iconv("utf-8", "gb2312", $fileName);
    //重命名表
    // $objPHPExcel->getActiveSheet()->setTitle('test');
    //设置活动单指数到第一个表,所以Excel打开这是第一个表
    $objPHPExcel->setActiveSheetIndex(0);
    ob_end_clean();
    ob_start();
    header('Content-Type: application/vnd.ms-excel');
    header("Content-Disposition: attachment;filename="$fileName"");
    header('Cache-Control: max-age=0');
    $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
    $objWriter->save('php://output'); //文件通过浏览器下载
    exit;

}

前台html里直接调用就可以了
