is there a function that one can use in (for example) an echo or print
command for debugging that will return the name of the function?
For instance
<?php
function abc(){
echo my_name_is();
return 0;
}
function def(){
echo my_name_is();
return 2;
}
<?
I guess I could hardcode the function name in the echo statement, but I
like messing around. :) I did look at php.net for a while but couldn't
find anything.

name of WHAT function.
The function you are in?
Sort of stack tracer ;-)
I found it more useful to make a little 'errprint' function.
And print a number or a message in a little box at the corner of the
screen, using something like a scrollable div
So
errprint: OK- 1
errprint: done the dirty bit
errprint: OK-2
errprint: OK-3
errprint: Oh shit.
etc.
call it with e.g. errprint('OK-1')

Try debug_backtrace(). Or more specifically
function xxx()
{
/* 0 index is top of the stack, which I kinda don't like, when you
* think about pushing and popping on a call stack...
*/
$me = array_shift(debug_backtrace());
echo $me['function'];
}

Doh! I should actually read the manuals for the functions I suggest!
You can also use __FUNCTION__, which is by far much simpler :)

Nice! Thanks. I'll also look into the debug_backtrace, but that's
exactly what I was looking for.
