warehouse check function

[pok4]

Hi guys,
I want a php script for check that item can fit in warehouse. I have $items variables (x,y,and warehouse items)
I found old ones (smartsearch) but they is very old...
Item lenght is 32 (s6 e3 xteam)

Here is example: https://pastebin.com/kmrwxb5r

I need a function because i make a shop and i want to check before update warehouse with new items.
Thanks in advance :)
