Normally, the method of the parent class can be prompted. here, only one Index is prompted.
Then I looked at the TP core directory, which has the assign method, that is, it cannot be called.
2: Then I manually $ this-> display without prompting, and then prompt that the template does not exist,
The template does not exist [D:/wamp/www/Tphp/Tpl/Home/Hello/index. tpl]
But there is such a file in this directory.
In addition, my actions are red. phpstorm is used, and no error is found...
Red is not noticed after the prompt...
