PHP: Get the name of the calling function?

Question

Is there a way to get the name of the calling function in PHP?

In the following code I am using the name of the calling function as part of an event name. I would like to modify the getEventName() function so that it can automatically determine the name of the calling method. Is there a php function that does this?

class foo() { public function bar() { $eventName = $this->getEventName(__FUNCTION__); // ... do something with the event name here } public function baz() { $eventName = $this->getEventName(__FUNCTION__); // ... do something with the event name here } protected function getEventName($functionName) { return get_class($this) . '.' . $functionName; } }

Have a look at the output of debug_backtrace().

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

<?php /** * Returns the calling function through a backtrace */ function get_calling_function() { // a function x has called a function y which called this // see stackoverflow.com/questions/190421 $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']) . ')'; } return $r; } ?>
