Article Introduction：Custom exception classes in PHP allow developers to create application-specific exception types, adding additional information and handling logic. By inheriting from the Exception class, a custom exception class can contain properties (such as error codes) and methods (such as getting error details). This enhances PHP's exception handling mechanism, provides a more flexible and customizable exception handling method, and improves the robustness, readability, and maintainability of applications.

The function used to define the top-level exception handler is set_exception_handler("My_exception" ); My_expection here is a developer-defined exception handling function, which is a top-level exception handler. Only when there is no function in the program to handle exceptions can the top-level exception handler handle exceptions.
