How to get current recursion level in a PHP function

Question

How to get current recursion level in a PHP function ? I mean, is there any \"magical\" (or eventually normal) function like this :

function doSomething($thi

You need to count it yourself, the only alternative would be something like XDebug which profiles your complete software. But this is highly inefficient.

 $v) {

        }
    }
    else {
        echo $counter;
        --$counter;

        // If we're returning (only PHP 5.5+)
        try {
            return $counter;
        }
        finally {
            --$counter;
        }
    }
}

?>

This allows you to count without a second public parameter.
