Problem with set_exception_handler

[nuxy]

I have a problem with the function set_exception_handler.

I can't seem to get it to work with it calling a function within a class.

 

set_exception_handler($en->handle_error);

When I try it that way, it reads the "error_handler" as a variable.

Notice: Undefined property: engine::$handle_error in index.php on line 19

 

set_exception_handler($en->handle_error());

When I try it that way, it reads as a function, but doesn't pass any variables to the function.

Warning: Missing argument 1 for engine::handle_error(), called in index.php on line 19 and defined in classes\engine.php on line 279
Warning: Missing argument 2 for engine::handle_error(), called in index.php on line 19 and defined in classes\engine.php on line 279
Warning: Missing argument 3 for engine::handle_error(), called in index.php on line 19 and defined in classes\engine.php on line 279
Warning: Missing argument 4 for engine::handle_error(), called in index.php on line 19 and defined in classes\engine.php on line 279

 

I have tried with just making a function in the "index.php" script, but it doesn't display anything then.

function handle_error($a, $b, $c, $d) {
global $en;
$en->handle_error($a, $b, $c, $d);
return;
}
set_exception_handler('handle_error');

 

Does anyone have an idea how I could fix this problem?
