How to get the current class name and method name in php

Getting method: 1. Use the magic constant "__CLASS__" to get the current class name (including the scope or namespace of the class); 2. Use "__FUNCTION__" to get the name of the current method; 3. Use "__METHOD__" to get the current method name (including class name).

In PHP, you can use magic constants to obtain Class name and method name.

Magic constants are special predefined constants that can change depending on where they are used. Magic constants usually start with two underscores __ and end with two underscores __.

The magic constants that can get the class name and method name are: "__CLASS__", "__FUNCTION__" and "__METHOD__"

• __CLASS__: The current class name (including the scope or namespace of the class);

  Since PHP 5, this constant returns the name when the class was defined (case-sensitive). In PHP 4 this value is always lowercase.

• __FUNCTION__: The name of the current function (or method);
  

• ##__METHOD__: Current method name (including class name);

  Returns the name when the method was defined (case-sensitive).
