篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了ThinkPHP5调用PHPExcel类实现导入导出相关的知识，希望对你有一定的参考价值。
注意：extend是放置第三方类的地方，不要乱配置命名空间那些，引起不必要的类错误
代码如下
<?php namespace app\\index\\controller; use think\\Controller; use think\\Db; use think\\Loader; use think\\Request; //use lib\\PExcel; class Four extends Controller { //上传页面展示 public function index(){ return view(); } //实现excel的导入操作 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; // } //防止乱码 ini_set(\'memory_limit\', \'1024M\');//设置php允许的文件大小最大值 Loader::import(\'PHPExcel.Classes.PHPExcel\');//必须手动导入，否则会报PHPExcel类找不到 header("Content-type:text/html;charset=utf-8"); //接收文件 $file = $_FILES[\'excel\']; $extension = strtolower( pathinfo($file[\'name\'], PATHINFO_EXTENSION) ); //实例化主文件 $phpExcel = new \\PHPExcel(); //创建读入器 if($extension==\'xlsx\'){ $objRender = \\PHPExcel_IOFactory::createReader(\'excel2007\'); }else{ $objRender = \\PHPExcel_IOFactory::createReader(\'Excel5\'); } //读取excel文件 $ExcelObj = $objRender->load($file[\'tmp_name\']); //查看有几个sheet $sheetContent = $ExcelObj->getSheet(0)->toArray(); unset($sheetContent[0]); //取出文件的内容描述信息 //$sheetColumn = $objRender->listWorksheetInfo($file[\'tmp_name\']); foreach ($sheetContent as $k => $v){ $arr[\'uname\'] = $v[0]; $arr[\'sex\'] = $v[1]; $arr[\'age\'] = $v[2]; $arr[\'class_name\'] = $v[3]; $res[] = $arr; } if(Db::name(\'excel_upload\')->insertAll($res)){ $this->success("导入成功"); }else{ $this->error("导入失败"); } //echo $sheetColumn[0][\'totalColumns\'];die; }

重点看前两个方法
uploadExcel
excel_download
