Excel匯入匯出功能我們經常用到，下面記錄自己的實現方法。Helper類PHPExcelHelper 可以直接拿過來使用。在控制器中實現資料組裝，model中實現資料驗證，最後匯入或匯出。

helper類中匯出匯入的寫法

namespace app\common\helper;

use app\common\constant\SystemConstant;
use PHPExcel;

trait PHPExcelHelper
{
    /**
     * excel表格匯出
     * @param string $fileName 檔名稱
     * @param array $headArr 表頭名稱
     * @param array $data 要匯出的資料
     * @author static7
     */
 

    private function excelExport($fileName = '', $headArr = [], $data = [])
    {
        $objPHPExcel = new PHPExcel();
        $objPHPExcel->getProperties();
        $keyA = ord("A"); // 設定表頭
        foreach ($headArr as $v) {
            $colum = chr($keyA);
            $objPHPExcel->
 
setActiveSheetIndex(0)->setCellValue($colum . '1', $v);
            $objPHPExcel->setActiveSheetIndex(0)->setCellValue($colum . '1', $v);
            $keyA += 1;
        }

        $column = 2;
        $objActSheet = $objPHPExcel->getActiveSheet();

        foreach ($data as $key => $rows
 
) { // 行寫入
            $span = ord("A");
            foreach ($rows as $keyName => $value) { // 列寫入
                //判斷資料是否有陣列，如果有陣列，轉換成字串
                if(is_array($value)){
                    $value = implode("、", $value);
                }
                $objActSheet->setCellValue(chr($span) . $column, $value);
                $span++;
            }
            $column++;
        }

        $fileName .= "_" . date("Y_m_d", time()) . ".xls";
        //$fileName .= "_" . date("Y_m_d", Request()->instance()->time()) . ".xls";
        //$fileName = iconv("utf-8", "gb2312", $fileName); // 重命名錶

        $objPHPExcel->setActiveSheetIndex(0); // 設定活動單指數到第一個表,所以Excel開啟這是第一個表
        header('Content-Type: application/vnd.ms-excel');
        header("Content-Disposition: attachment;filename=" . $fileName);
        header('Cache-Control: max-age=0');
        $objWriter = \PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
        $objWriter->save('php://output'); // 檔案通過瀏覽器下載
        exit();
    }

    //匯入函式
    private function excelImport($file)
    {
        header("content-type:text/html;charset=utf-8");
        //檔案上傳到伺服器,返回檔案的路徑
        $info = $this->uploadFile($file);
        //$objPHPExcel = new PHPExcel();

        //獲取檔案字尾
        $suffix = $this->getExtension($info);
        //判斷哪種型別
        if ($suffix == "xlsx") {
            $reader = \PHPExcel_IOFactory::createReader('Excel2007');
        } else {
            $reader = \PHPExcel_IOFactory::createReader('Excel5');
        }

        //載入excel檔案
        $file_path = public_path().'public\storage\\'.$info;
        //$file_path = root_path() . "public\storage". $info;
        $excel = $reader->load($file_path);
        //讀取第一張表
        $sheet = $excel->getSheet(0);
        //獲取總行數
        $row_num = $sheet->getHighestRow(); //var_dump($row_num);die;
        //獲取總列數
        $col_num = $sheet->getHighestColumn();
        if($sheet){
            return $sheet;
        }else{
            return false;
        }
    }
  }

在控制器中
匯出

    public function export(Request $request)
    {
        $ids = $request->post('ids');
        $user = UserModel::field('id,user_name,account,sex,phone,email,pid as post,oid as organization,star,is_post');

        //如果有選擇時，匯出部分
        if (!empty($ids)) {
            $user = $user->whereIn('id',$ids)->select()->toArray();
        }else{
        //匯出全部
            $user = $user->select()->toArray();
        }

        $headArr = ['ID', '姓名', '帳號', '性別', '手機號', '郵件', '崗位', '部門', '星級', '是否在職'];
        $fileName = '成員表資訊表';

        if (empty($user)) {
            ajaxR(SystemConstant::SYSTEM_FAILURE, 'no data');
        }

        $res = $this->excelExport($fileName, $headArr, $user);

        if ($res) {
            ajaxR(SystemConstant::SYSTEM_SUCCESS, 'ok', $res);
        } else {
            ajaxR(SystemConstant::SYSTEM_FAILURE, '匯出失敗');
        }

    }

匯入寫法

    public function import(Request $request)
    {
        $file = $request->file('user_file');
        if (empty($file)) {
            ajaxR(SystemConstant::SYSTEM_FAILURE, 'File empty!:(');
        }
