PHP allows functions and classes to have the same name, but may cause readability and maintenance issues. For example: 1. It is difficult for other developers to determine whether the call is a function or a class; 2. It is easy to be confused when IDE is automatically completed; 3. There may be conflicts when project expansion. Although the syntax is correct, such as the function User() coexisting with the User-like and the parser can distinguish it, it is recommended to avoid problems through naming specifications, document descriptions, namespaces, etc., or use different names to improve clarity and security.

function is an independent function, suitable for general functions; method is part of the class, suitable for encapsulating object behavior. Function can be called directly, with global scope, cannot access class attributes, does not support object-oriented features, and is suitable for small scripts; method needs to be called through objects or classes, belongs to the class, can access private attributes, supports inheritance polymorphism, and is suitable for large project structures. Function or method should be used according to whether the status and encapsulation are required.

To create a PHP function that accepts callbacks and their parameters, 1. Use call_user_func_array() to call dynamic callbacks and pass parameter arrays; 2. Verify whether the callback is legal through is_callable() to avoid invalid calls; 3. Support closures, object methods and static methods to improve flexibility. For example: define the run_callback($callback,$args) function, first check the validity of the callback, and then use call_user_func_array() to execute, support multiple calling forms such as functions, methods and closures, and can pass in parameter arrays to ensure that the system is scalable and safe.
