The difference between include () and require ()

are used to include and run the file.

The difference 1:include () only generates a warning that the program will continue to run;

Require () generates a fatal error and the program stops running.

The difference between 2:include () can be referenced when needed, and can be included in an expression (such as an if () statement) or in a function;

Require () is generally referred to directly at the very beginning, even if it does not need to be executed in the row.
