PsySH is a runtime developer console and interactive debugger for PHP. It is an open-source, interactive shell that allows developers to explore and debug their PHP code in real-time.

When you run the "psysh" command in the terminal, it starts the PsySH shell, providing you with a command-line interface where you can execute PHP code interactively. It allows you to enter PHP expressions and statements, and immediately see the output and result of those expressions. It can be useful in testing and experimenting with PHP code without the need to write a complete script or reload the entire application.

PsySH provides features like tab completion, history browsing, automatic syntax highlighting, and various convenience functions, making it a powerful tool for PHP developers to debug and analyze their code. It also provides access to the entire application state, allowing you to inspect variables, objects, and their properties, and even modify them on the fly.

Overall, PsySH offers a more interactive and dynamic way of working with PHP code, which can greatly enhance the development and debugging process.
