finding function names

[blockage]

Is there any way of finding out the name of a function programmatically? Is there for instance, anyway to do something like this?

function john_doe()
{
   echo get_function_name();
}
john_doe();

// Desired output
john_doe

Even more useful might be...

function johin_doe()
{
   debug();
}

function debug()
{
   echo refering_function_name();
}
john_doe();

// Desired output
john_doe

Right now it's not possible to do that. When PHP5 comes out, you'll have the ability of back-tracing the stack, so maybe then you can do what you want to do.

No good to me as I use version 4.1.2.

Anyhow I just found this (http://www.php.net/manual/en/language.constants.predefined.php), in 4.3 the php gods created this magic constant...

__FUNCTION__

...So if you're using 4.3 you can...

function john_doe()
{
   echo __FUNCTION__;
}
john_doe();

// Output: 

john_doe

Yeah, but inside debug(), you can't use FUNCTION to get "john_doe", unless you pass it.
