functional-php

One nitpick from the article, PHP does have first class support for functions in the language. Functions are available in a few different ways: - Normal function declaration in global and "module"/namespace scope. - Anonymous functions that can also be assigned to variables (except in a few cases, like object properties) - Anything extending the Closure class The last one is obviously a nod at what is going on under the hood, but as far as the developer writing the code is concerned, it doesn't matter. A library even exists to explicitly provide some functional programming functions under a namespace for easy inclusion with other projects. There is no requirement that all functions must be defined in a namespace, as evidenced by the first 10 years of crappy PHP code littered with functions in the global namespace! https://github.com/lstro

PHP has this https://github.com/lstrojny/functional-php

Yep that's a great library, I'd like to see some of it in core. Same with this: https://github.com/lstrojny/functional-php which overlaps somewhat. The no-brainers to me are the missing array_some()/array_any() array_every()/array_all() and an array_search() that takes a predicate and iterable. I do these now in userland but an optimized native version would be nice.

Another awesome functional library / extension for PHP is https://github.com/lstrojny/functional-php

Why not using namespaced functions instead of static methods all in the same class ? This would have allowed to add new functions. This would even have allowed to use the _ namespace. With namespaces: namespace _; function each() { } // chaining can be achieved with this: class Wrapper { private $coll; function __construct($coll) { $this->coll = $coll; } function __call($name, $args) { array_unshift($this->coll,$args); return new self(call_user_func_array('_\\'.$name, $args)); } } function __($coll) { return new Wrapper($coll); } use _; _\each(...); // or __($coll)->each(...); // I can add new functions namespace _; function something(){} With static methods: class __ {
