🧭 What Does phpstan Actually Do? — A Plain-English Guide

In simple words: phpstan is a tool made for people who build software, for testing mobile apps to find mistakes before users do. It is completely free and open source — its code is public on GitHub, where 14,146 people have bookmarked it as worth using.

Step by step — how you would actually use it

1. An honest note first: phpstan is made for programmers and system administrators, not for everyday clicking.
2. They install it on their computer or server, following its README.
3. They connect it to their project or system, usually with a few settings or commands.
4. From then on, it helps them with testing mobile apps to find mistakes before users do as part of their daily technical work.
5. Everyday users meet this tool only indirectly — inside the apps and websites it helps to build and keep running.

💡 A real-life example: A student with an app idea uses a framework like this to build one app that works on both Android and iPhone.
