MadLisp is a Lisp interpreter written in PHP.
The project requires PHP 7.4 or newer and Composer.
Create a new directory and require the project using composer:
$ mkdir mylisp
$ cd mylisp
$ composer require peklaiho/madlisp
Use the vendor/bin/madlisp executable to start the interpreter. Start the REPL with the -r option:
$ vendor/bin/madlisp -r
>
You can evaluate Lisp code interactively inside the REPL:
> (+ 1 2 3)
6
Alternatively you can evaluate a file that contains Lisp code:
$ echo "(+ 1 2 3)" > mylisp.mad
$ vendor/bin/madlisp mylisp.mad

The full documentation is available on the project website.
The language seems stable at this point so I am releasing it as 1.0. Please report any issues.
