PHPexcel(ThinkPHP5.0框架)批量導入mysql數據庫

1.下載PHPexcle類庫,放到extends 目錄下

前端代碼

    <form id="upload" action="import_excel" method="post" enctype="multipart/form-data">
        導入商會信息:<input type="file" name="file" id="file">   <input type="submit" name="submit" value="上傳EXcel文檔" />
    </form>

後端代碼

   //導入excel文檔
    public function import_excel(){   
        header('Content-type: text/html; charset=utf-8'); //設置頁面編碼

        }       
        if(!is_writable($save_path)){       //給目錄存在沒有權限
            chmod($save_path, 0777);
