Phel is a functional, Lisp-inspired programming language that compiles to PHP. It brings the expressive power of Clojure and the simplicity of Janet to the PHP ecosystem — enabling you to write concise, immutable, and composable code that runs anywhere PHP does.

Example

; Define a namespace
(ns my\example)

; Define a variable with name "my-name" and value "world"
(def my-name "world")

; Define a function with name "print-name" and one argument "your-name"
(defn print-name [your-name]
  (print "hello" your-name))

; Call the function
(print-name my-name)
