ThinkPHP5調用PHPExcel類實現導入導出

注意：extend是放置第三方類的地方，不要亂配置命名空間那些，引發沒必要要的類錯誤

 

代碼以下

<?php
namespace app\index\controller;
use think\Controller;
use think\Db;
use think\Loader;
use think\Request;
//use lib\PExcel;

class Four extends Controller
{
    //上傳頁面展現
    public function index(){
        return view();
    }

    //實現excel的導入操做
    public function uploadExcel(){
//        //接收文件
//        $file = request()->file('excel');
//        $info = $file->validate(['size'=>3145728,'ext'=>'xlsx,xls,csv'])->move(ROOT_PATH . 'public' . DS . 'static' . DS . 'excels');
//        if($info){
//            $excel_path = ROOT_PATH.'public'.DS.'static'.DS."excels".DS.$info->getSaveName();
//        }else{
//            $excel_path = null;
//        }
        //防止亂碼
        ini_set('memory_limit', '1024M');//設置php容許的文件大小最大值
        Loader::import('PHPExcel.Classes.PHPExcel');//必須手動導入，不然會報PHPExcel類找不到
        header("Content-type:text/html;charset=utf-8");
        //接收文件
        $file = $_FILES['excel'];
        $extension = strtolower( pathinfo($file['name'], PATHINFO_EXTENSION) );
        //實例化主文件

        }else{

        }
        //讀取excel文件
        $ExcelObj = $objRender->load($file['tmp_name']);
        //查看有幾個sheet
        $sheetContent = $ExcelObj->getSheet(0)->toArray();

            $arr['class_name'] = $v[3];
            $res[] = $arr;
        }

        if(Db::name('excel_upload')->insertAll($res)){

            $this->error("導入失敗");
