Cannot declare class app\home\controller\Cases because the name is already in use

命名空间冲突了 use 模型类的时候使用as别名

同一个页面上命名空间不同类名一样就会混淆参考PHP手册

1.在控制器中使用 as 别名；

$Cannot declare class app\home\controller\Cases because the name is already in use$

2，在控制器中自定义模型

2 $Cannot declare class app\home\controller\Cases because the name is already in use$

3，控制器中调用“getBy+字段”方法

$Cannot declare class app\home\controller\Cases because the name is already in use$
