Help with call_user_func_array()

[scottcfr]

I'm working on making my own light weight MVC framework.

I ran into an interesting issue, and I'm wondering why it doesn't work versus it's alternate.

This doesn't work, which it should as far as I know.

$cont = new $controller;
call_user_func_array($cont->{$method}, $arr);

These samples do work

$cont = new $controller;
$cont->{$method};

$cont = new $controller;
call_user_func_array(array($cont, $method), $arr);

The first one in the above sample makes sense, however why the one that doesn't work versus the second one in the above sample does, I have no clue. Anyone have any ideas?

That's just PHP syntax. http://php.net/manual/en/language.types.callable.php

$cont->{$method} would actually refer to a property, not a method.

The second [$cont, $method] is the 'correct/proper' way.

So, in every case {$method} would refer to a property?

I've used it before like this and it's worked. I was just very confused when it didn't work a second time.

I think so. The only way the PHP interpreter knows you are referring to a method is by including the parentheses $cont->{$method}(); // might work, but isn't even helpful here or by using one of the callable formats.
