1. Think about how we write the entry file in php. We may need to add an app::run();
at the end.
It is completely unnecessary in 3.0. You will find that otherwise there will be two calls to 2.debug. When we were developing, we usually wrote like this in 2.0, config.php under conf
But the declaration method in 3.0 is different now, we use define(‘APP_DEBUG’,true);
This is how to state it
3. When assigning templates to templates, in 2.0 we will write these $this->display(skin@module:method);
But in 3.0 we have $this->display(skin:module:method);
4. When we call the model, we may do this $user=D('user'); This is completely fine in 2.0, but
If you write on 3.0, I’m sorry that the model method you wrote in UserModel.php cannot be called at all. What should I do about this?
$user->D(‘User’); don’t ignore case
The deployment directory of 5.3.0 is different from that of 2.0. You have to check it out for yourself
The custom directories or paths of 6.3.0 are different from those of 2.0. You should check the manual reference. In fact, you can also write it yourself
That’s all for today, please continue updating slowly~~
