<?php
namespace?app\index\controller;
use?app\common\controller\Index??as?commonIndex;
class?Index

????public?function?index()
????{
????????return?"this?is?index?Index?index";
????}
????public?function?common()
????{
????????$common?=?new?commonIndex();
????????return?$common->index();
????}
}

這是哪出錯(cuò)了為啥顯示Class?'app\common\controller\Index'?not?found
