On one hand, yes, your right.

Since I called the function, I should know what its name is.

What I'm trying to do is a "trace" display.

When I turn on $Trace = true, each function, in turn, will display its name
as each is called.

Right now, I'm using this...

   if ($GLOBALS["TRACE"])
      echo 'foobar()' . '<br />';

Yes this works, but, being the lazy sod I am, I'd like to have PHP do more
of the work for me...

   if ($GLOBALS["TRACE"])
      echo <auto_function_name>' . '<br />';

I use this on each file...

   if ( ( isset ( $GLOBALS["TRACE"] ) ) && ( $GLOBALS["TRACE"] ) )
      echo __FILE__ . '<br />';

But, I guess this is not possible in PHP, based upon the few responses given
to date.

Thanks anyway.
