Thanks, Justin; that occurred to me, too. But the following results in
"Notice: Undefined variable: factorial":
$factorial = function($n) use ($factorial) {
if ($n == 1)
return 1;
else
return $n * $factorial($n - 1);
};
print $factorial(3);
and eventually "PHP Fatal error: Function name must be a string."
