[RFC] Fibers — . : Swoole:
Once PHP has a stack coroutine like Fiber, we can do more than what we can do now. Since we can interrupt from PHP internal functions, then we can replace all the implementation of PHP blocking functions, such as sleep(), and we can also replace php_stream so that we can change the implementation of PDO, mysqli, and phpredis into a coroutine way, and we can also make curl become a coroutine version through libcurl's support for multiplexing.

Symfony

Phel - Bahasa pemrograman fungsional yang dikompilasi ke PHP. Ini adalah dialek Lisp dan terinspirasi oleh Clojure. Kode sampel:

Teks tersembunyi

# 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)
