We know that in PHP, the error message can be silent through the error blocker. how does it work?

During syntax analysis,:

Two Opline (operations) will be inserted before and after the include statement respectively. These two operations are done respectively:

1. save the current error_reporting value and set error_reporting (0); // disable error output 2. restore the previously saved error_reporting value, that is, the above code is similar to the following code:

$ Old = error_reporting (0); include ('file'); error_reporting ($ old); also, let's say: "When Will error suppression be applied ?", My personal suggestion is that if an error in this statement does not affect you much and you do not care about the error, you will not arrange additional logic to handle the error, then you can use error suppression. otherwise, use additional logic to identify errors.
