thinkphp5.1 Excel导入导出

PHPExcel下载地址：PHPExcel下载地址

thinkphp 5.1版本取消`Loader :: import`方法以及`import`和`vendor`助手函数，推荐全部使用命名空间方式的类以及自动加载机制，如果必须使用请直接改为php内置的`include`或者` require`语法。

导入：

<？php 
//导入
public function upload() 

{
        //获取表单上传文件
        $file = request()->file('excel'); 
         if($file){
             $file_types = explode(".", $_FILES ['myfile'] ['name']); // ["name"] => string(25) "excel文件名.xls"
            $file_type = $file_types [count($file_types) - 1];//xls后缀
            /*判别是不是.xls文件，判别是不是excel文件*/
            if (strtolower($file_type) != "xls" && strtolower($file_type) != "xlsx") {
                $this->error('不是Excel文件，重新上传');
                die;
            }

            $a = dirname($_SERVER['SCRIPT_FILENAME'])."/";
            $b = dirname(realpath($ a))."/";

            $path = $b.'public/upload/excel'; 
            $info = $file->move($path); 
            $file_path = $path.'/'.$info->getSaveName(); //上传后的EXCEL路径
            switch ($extension) {
                case 'xls':
                    $type = 'Excel5';
                    break;
                case 'xlsx':
                    $type = 'Excel2007';
                    break;
            }

            // 引入核心文件
            require'../extend/PHPExcel/PHPExcel.php'; 
            $objReader = \PHPExcel_IOFactory::createReader($type);

            $obj_PHPExcel =$objReader->load($file_name, $encode = 'utf-8');  //加载文件内容,编码utf-8
            /*$sheet = $obj_PHPExcel->getSheet(0); //激活当前的表
            $highestRow = $sheet->getHighestRow(); // 取得总行数
            $highestColumn = $sheet->getHighestColumn(); // 取得总列数*/


            $excel_array=$obj_PHPExcel->getsheet(0)->toArray();   //转换为数组格式
            array_shift($excel_array);  //删除第一个数组(标题);

        } 
    }
