TP is annoying, with a large number of broken people

Php constants cannot be placed in strings!
Put it in a string as a character

TP uses strings to replace the pseudo constants created, confusing many people

I tried a few times but it is still not easy to use. maybe I didn't understand what you mean. I am a newbie. please give an example.

What is the output using the code {$ Think. const. IMG_URL} above?

Check whether the config file is defined?

Sorry, I didn't understand the TP execution process. I thought it was require '. /ThinkPHP. php '; can be put at will, the original need to define the constant and then require. After this order is adjusted, the above usage will be fine. It's annoying for the moderator.
