Course Introduction:Hook functions allow developers to extend or modify the behavior of existing functions by injecting custom code before and after other functions are executed. The following syntax can be used to create a hook function: function function name ($args) {//custom code}, where $args is the parameter array of the original function. For example, you can create a hook function to track the function execution time: functiontrack_function_time($args){//custom code}, and then apply this hook before the call_user_func_array function to record the function execution time.

Course Introduction:Hook functions in the Go language can be called when the program executes specific events and are used to customize program behavior, such as adding additional logic. To create a hook function, you need to define a function that implements the io.Reader or io.Writer interface and use it by passing the hook function as a parameter. Practical examples include monitoring I/O operations (recording read and write data and execution time) and customizing logging (adding more information or changing log levels). Using hook functions enhances the functionality and customizability of your program.
