THANKS FOR THE HELP!

The most help I can give you is to tell you to learn some more PHP.

Las help pls men, i promise ill study php

Expected Item[]
That means, you should pass an array of Item objects.

WAT?

You sure? Because the teleport sends me to the sky limit haha look at the log

1. Unnecessary parentheses in line 1
2. Inventory->addItem() accepts varargs Item objects as the argument. You can pass items like this:
   PHP:

   $inventory->addItem($item0, $item1);
   or if you have an array of Item objects $items, pass them like this:
   PHP:

   $inventory->addItem(...$items);
[/LIST]
