Phel, a native Lisp for PHP
#1about 2 minutes
Introducing Phel, a Lisp dialect for the PHP ecosystem
Phel is a functional programming language inspired by Clojure that transpiles directly to PHP, making it fully interoperable.
#2about 1 minute
Comparing functional and object-oriented paradigms
Functional programming emphasizes immutable data and declarative code with no side effects, contrasting with object-oriented programming's mutable state.
#3about 1 minute
Understanding the basic syntax of Phel with an example
A "Hello World" example demonstrates Phel's Lisp-like syntax, including namespaces, defining constants, and creating and calling functions.
#4about 2 minutes
Exploring Phel's data types and control flow statements
Phel includes basic types, persistent data structures like lists and maps, and control flow statements such as `if`, `case`, and `loop`.
#5about 1 minute
Using native PHP functions and classes within Phel
The `php/` prefix allows full interoperability, enabling the use of any native PHP function, class, or object directly from Phel code.
#6about 2 minutes
A live demo of a snake game built with Phel
A demonstration showcases a complete snake game running in the terminal, built entirely in Phel to illustrate its practical application.
#7about 1 minute
The project's goal and community resources for learning
Phel aims to introduce functional programming concepts to PHP developers rather than replace PHP, with resources available on GitHub and Gitter.
