composer require "phpoffice/phpexcel" 用这个命令下载就可以（等一会时间）,前提是你已经安装的composer 如果没有，就安装一个，就不多说了。
安装完成后 window 下打开命令窗口 输入compposer 查看是否安装成功,然后打开你的yii2.0(高级版)框架的verdor 这个文件夹 Shift+右键，打开命令窗口，运行上面那个下载命令他就会自动下载并配置好了。 如果出现phpoffice这个文件夹就对了(里面有PHPExcel 这个文件)。
然后在Controller里面引入 use \PHPExcel; 记得要加“\”哦。 然后在方法里实例化就可以了，在具体的excel方法前面也要加‘\’不然会报错。
最后就是导出了， 这个比较简单 这 只是一个简单的例子
/**

*/
public function actionExcel()
{
$time = date('Y-m-d H-i-s', time());
$names = $time . '设备数据' . '.xls';
$objPHPExcel = new \PHPExcel();
$query = new \yii\db\Query();
$query = $query->select("t1.*, t2.series_name, t2.series_model, t2.series_rows")
->from(['t1' => 'ss_equipment'])
->leftJoin(['t2' => 'ss_series'], "t1.series_id = t2.id")
->where(1);
$list = $query->all();
/*以下就是对处理Excel里的数据， 横着取数据，主要是这一步，其他基本都不要改*/
foreach($list as $k=>$v) {
$num= $k+1;
$objPHPExcel->setActiveSheetIndex(0)
//Excel的第A列，uid是你查出数组的键值，下面以此类推

header('Cache-Control: max-age=0');
$objWriter = \PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
$objWriter->save('php://output');
return $this->returnData('', 1, '导出成功');
}上面是快速导出,下面是(图片加设置宽高水平垂直居中)
