get name of function within function

Is there a way to find out the name of the function within the
function?

I'm doing troubleshooting of a page in which I call a lot of
functions. I had a simple error message pop up, which was okay back
when the page way simple. Now that the page has grown, it's a PITA to
find out where exactly the error message is being triggered. It would
be very helpful if I could find out which function I'm "in" when the
error message gets called.

Or alternatively, do a debug_print_backtrace();, very nice when
troubleshooting.

You have a magic constant called __FUNCTION__ but what really want is a
backtrace:

http://php.net/debug_backtrace

You can call it from your own error handling function:

http://php.net/set_error_handler
http://php.net/set_exception_handler

Best option for programmers, definately. For users, sometimes a
completely bizzare error message that doesn't mean ANYTHING gets better
reporting. "lock timeout" gets much less attention from users than "Why
did it just say it was out of tuna?", and since *I* know where the tuna
error message is, even though the message is actually "fainted from loss
of tuna", I can still find exactly where the failure was, and know what
to look for in logs.
