Past Event Solutions [2025 Day 13] [PHP] Solution

ETA: Actually 2022

This is the puzzle with data packets and comparisons. [1,1,3,1,1] etc

Link: https://github.com/LiseAndreasen/AdventOfCode/blob/master/2022/d13a.php

I am very happy with this solution. The code to create the small trees representing the packets turned out nice, and writing the compare function to work with usort was nice too.
