What about:
$backtrace=debug_backtrace();
echo $backtrace[0]['function'];
That seems to be also the common solution for getting the name of the calling
function.

could you explain a little more: what i " some interesting dynamic behavior" ?
I mean , the real use case.

Description:
------------
I would like my trait functions to know what alias (if any) was used to call them.
The idea came from discovering that you can give a trait function multiple aliases (see Test
Script).
It occurs to me that you could have some interesting dynamic behavior if the trait function was able
to determine what name (alias) was used to call it.
If possible, a new constant __ALIAS__ could be created to store this value.
Thank you for your consideration.
Test script:
---------------
<?php
trait TestTrait
{
public function test() { print __FUNCTION__ . ', ' . __ALIAS__ . "\n"; }
}
class TestClass
{
use TestTrait { test as test2; test as test1; }
}
$c = new TestClass();
$c->test1();
$c->test2();
Expected result:
----------------
test, test1
test, test2
Actual result:
--------------
test, __ALIAS__
test, __ALIAS__
------------------------------------------------------------------------
