获取当前正在执行的方法

Question

I'm fairly new to OOP and I'm trying to get the name of the currently executing class and method. For example:

<?php

class ParentExample
{
    function __construct()
    {
        echo get_class($this) . '<br />';
        echo __METHOD__;
        exit;
    }
}

class ChildExample extends ParentExample
{
    public static function test()
    {
        echo 'hello';
    }
}

call_user_func_array([new ChildExample, test]);

This is the result I want:

ChildExample
ChildExample::test

This is the result I get:

ChildExample
ParentExample::__construct

I've looked at debug_backtrace() but I don't understand how to decipher the results or if that's even what I need. Is there an easier way to achieve what I'm after?

EDIT: Based on the answers I think my question isn't clear. I want the ParentExample constructor to tell me the name of the called method. Is this possible?

Answer 1

I want the ParentExample constructor to tell me the name of the called method. Is this possible?

No, that is not possible. The constructor is executed when constructing the object and only then, this means it's executed before you can place any method calls on the object.

echo __METHOD__; is within the __construct method. Since __METHOD__ always has the value of the method it's in, it can't print `

__construct is called when you create the object. You create an object by using the new operator. This is not connected to the static test method.

You would have to put echo __METHOD__ into the test method for that to happen ;)

You should use a string to specify the name of the method:

call_user_func_array([new ChildExample, "test"]);
// Since you're not passing any arguments, this will do:
call_user_func_array([new ChildExample, "test"]);
