Question

thinkphp5.0 如何导入phpexcel插件，能详细些点吗

Answer 1

下载phpexcel，将整个文件夹放到vendor文件夹里面，如下图

在控制器中的使用方法

        vendor("PHPExcel.PHPExcel");
        $objPHPExcel = new \PHPExcel();
        $file_name = date('YmdHis').'.xls';
        header("Content-Disposition:attachment; filename=".$file_name);
        $objActSheet = $objPHPExcel->getActiveSheet()->setTitle('成绩单');


        $objActSheet->SetCellValue('A1', 'ID');
        $objActSheet->SetCellValue('B1', '名称');
        $objActSheet->SetCellValue('C1', '分数');

        $list = "";//数据列表

        if($list){
            foreach ($list as $k => $v){
                $i = $k + 2;
                $objActSheet->SetCellValue('A'.$i,''. $v['id']);
                $objActSheet->SetCellValue('B'.$i,''. $v['name']);
                $objActSheet->SetCellValue('C'.$i,''. $v['score']);
            }
            $objWriter = new \PHPExcel_Writer_Excel5($objPHPExcel);
            $objWriter->save('php://output');//输出到浏览器
            exit;
        }

Answer 2

一、下载完毕后解压文件得到以下几个文件夹选择黑色框里的文件放到thinkphp的框架系统目录下\Thinkphp\Library\Vendor\下

二、把Classes的文件名称改成PHPExcel

三、在公共控制器中加入导入导出公用代码

四、之后在你作为导出数据使用的控制器写入下列代码
//导入：

function impUser(){
if(isset($_FILES["import"]) && ($_FILES["import"]["error"] == 0)){
$result = $this->importExecl($_FILES["import"]["tmp_name"]);
if($result["error"] == 1){
$execl_data = $result["data"][0]["Content"];
foreach($execl_data as $k=>$v){
..这里写你的业务代码..
}
}
}
}

//导出：

function expUser(){//导出Excel
$xlsName = "User";
$xlsCell = array(
array('id','账号序列'),
array('account','登录账户'),
array('nickname','账户昵称')
);
$xlsModel = M('Post');
$xlsData = $xlsModel->Field('id,account,nickname')->select();
$this->exportExcel($xlsName,$xlsCell,$xlsData);
}

Answer 3

在tp5.0的根目录找到extend文件夹，然后将phpexcel文件夹放到这里面，然后项目里面引入

// 引入 extend/phpexcel/PHPExcel.php
import('phpexcel.PHPExcel', EXTEND_PATH);
//实例化PHPExcel
$objPHPExcel = new \PHPExcel();
