And also Items.xml parser, how it works :

The pull request comes with an already parsed items.xml (lastest one from otland github) (item_list.txt), Inside engine/function/itemparser/ theres a file called itemparser.php, you just need to run that php file everytime you modify your items.xml (from your otserver)
Theres also a file called itemlistparser.php that adds the following functions to ZnoteAAC

getItemNameById($id) and getItemIdByName($name) so you can do the following

getItemNameById(2160); //will echo Crystal Coin

This can be used for the Znote AAC shop / market to load item names using IDs
