Is there a function that can return the name of the current function a program is executing?

Yes, you can get the function's name with the magic constant __FUNCTION__

class foo
{
  function print_func()
  {
            echo __FUNCTION__;
  }
  function print_method()
  {
            echo __METHOD__;
  }
}

$obj = new foo();
$obj->print_func();      // Returns: print_func
$obj->print_method();    // Returns: foo::print_method

Maybe via debug_backtrace http://www.php.net/manual/en/function.debug-backtrace.php
