In PHP, getting the calling function

In PHP, if you want to know the function that called whatever function you are currently in, you can define something like:

* Returns the calling function through a backtrace
function get_calling_function() {
// a funciton x has called a function y which called this
  // see
$caller = debug_backtrace();
$caller = $caller[2];
$r = $caller['function'] . '()';
  if (isset(
$caller['class'])) {
$r .= ' in ' . $caller['class'];
  if (isset(
$caller['object'])) {
$r .= ' (' . get_class($caller['object']) . ')';
