If you don't have Docker yet, please consult my Install Docker and play with PHP post first.
When running Docker without specifying a volume, everything done during the execution of Docker is done in memory. In other words: if the PHP script you run from Docker creates folders or files, these will never be created on your disk. They will be created exclusively in memory.
Docker can be installed free of charge for personal or small-scale use: https://www.docker.com/products/personal/.
You can install it on Linux, Mac or Windows.
The easiest way, under Windows, is to use Docker Desktop.

By default, the Linux distribution is installed on your C: drive. If, like me, you have a D: drive with almost nothing on it, it can be really interesting to move Linux on that second drive.
Here are the steps I followed to create this blog.

When WSLg is enabled, it's possible to access to the graphical user interface of your Linux distribution (in my case, it's Ubuntu).
If you don't have xrdp yet, you can install it by running:
sudo apt update && sudo apt -y upgrade
sudo apt-get install -y xrdp
The situation: you wish to run a piece of standard PHP code (no dependency) like the one below:
<?php
echo "<h2>Incorrect, silent bug</h2>";
print_r(json_decode(utf8_decode("Ipso lorem"), true));
echo "<h2>Incorrect, we got an exception</h2>";
print_r(json_decode(utf8_decode("Ipso lorem"), true, 512, JSON_THROW_ON_ERROR));
