How to get the method name in a class in php

There are two ways for php to get the name of the method in the class: 1. Use the magic constant "__FUNCTION__" to return the name of the current method in the class. 2. Use the get_class_methods() function to get the names of all methods in the specified class and return an array containing all method names. The syntax is "get_class_methods('class name')" or "get_class_methods(new class name())".
