call_user_func() expects non-static method

[marquesine]

Why is that? Is it part of the last PHP 7.4 updates?

Setting public static funcion won't cause any future problems?

Also, it is curious that the error is pointed, but the return of the function still appears below it.

Isn't it better to instatiate SiteController, then call for it?

As follows:

$siteController = new SiteController();
$app->router->get('/contact', [$siteController, 'contact']);

You should not set public static function because you won't be able to use $this keywork inside controller methods.

I think you don't have latest version of the code.
In latest version it automatically instantiates controller instance and uses that.

Still curious on why it claims it has to be static method inside call_user_func().

I'll keep trying. So far, I have followed the tutorial by baby steps, and there it is working without the error.

Now I see the problem. @thecodeholic himself correct it around 1:11:15 of the freeCodeCamp.org youtube video.
