Is it possible to have a PHP function that is both recursive and anonymous (lambda). This is my attempt to get it to work, but it doesn't pass in the function name.
$factorial = function( $n ) use ( $factorial ) {
if( $n == 1 ) return 1;
return $factorial( $n - 1 ) * $n;
};
print $factorial( 5 );
I'm also aware that this is a bad way to implement factorial, it's just an example.
