Yii2使用PHPExcel报错：Class ‘PHPExcel‘ not found

一、解决

• 在 class 上面手动引入 require Yii::$app->basePath.'/../vendor/PHPExcel/Classes/PHPExcel.php'

二、代码

<?php

namespace backend\controllers;

use Yii;
use yii\web\Controller;

require Yii::$app->basePath . '/../vendor/PHPExcel/Classes/PHPExcel.php';


class TestController extends Controller
{
    
    
    public function init()
    {
    
    
    }

    //index方法
    public function actionIndex()
    {
    
    
        $objExcel = new \PHPExcel();
        $data = [];

        return $this->render('index', array('data' => $data));

    }
}
