Function/Global var to return name of calling function?

[Daniel Hansen]

I'm sure I saw this somewhere but can't remember where and can't find it now...

Is there a PHP function or global variable that will return name of the calling function? I want to do this for error reporting purposes without
having to hardcode the function name into my scripts.

Say the function is named getFunctionName(). I want to do something like...

function foo() {

Like way kewl, dewd...

<?php
function a() {
$c = getFunctionName();
print "The current function is $c<br>\n";
}

function getFunctionName() {
$backtrace = debug_backtrace();
return $backtrace[1]['function'];
}
a();
?>

Works like dream!

Thanks!

I **LOVE** it!

The code below generates the following log file entry (contants starting with "G" are defined elsewhere:
