The ___ROOT___ constant is not defined in thinkphp5.0.9, how to solve it

Question

Use of undefined constant ROOT - assumed '__ROOT__'
This is an error message. I am new to 5.0 and I don’t know if the constants in 5.0 can be used. Can they be redefined?

Answer 1

tp5 needs to be defined by yourself

直接在配置文件中添加：
'parse_str'=>[
'__PUBLIC__'=>'/public/',
'__ROOT__' => '/',
]
