Dsheiko\Extras

Collection of chainable high-order functions to abstract and manipulate PHP types. The library extends PHP types with JavaScript and Underscore.js methods

The packages takes its name from Array Extras referring to the array methods added in ES5 (JavaScript) to abstract generic array manipulation logic

Installation

Require as a composer dependency:

composer require "dsheiko/extras"

Highlights

Fixing PHP:
- Naming convention: all methods are camelCase styles vs PHP built-in functions in lower_case
- Consistent parameter order (Chain::chain($target)->method(...$options) or <Type>::method($target, ...$options))
- Methods are chainable
- Data structure PlainObject similar to JavaScript plain object
- Manipulation target (value) can always be as reference as well as type literal
Familiar syntax: JavaScript methods, in addition methods of Underscore.js/Lodash
Performance: package relies on PHP native methods; no foreach where a built-in specific function can be used

Overview

Examples

None-reference target

<?php
use \Dsheiko\Extras\Arrays;

function numToArray(int $num): array
{
  return [$num];
}
$res = Arrays::map(range(1,3), "numToArray"); // [[1],[2],[3]]

Chaining methods

<?php
use \Dsheiko\Extras\Any;

$res = Any::chain(new \ArrayObject([1,2,3]))
    ->toArray() // value is [1,2,3]
    ->map(function($num){ return [ "num" => $num ]; })
    // value is [[ "num" => 1, ..]]
    ->reduce(function($carry, $arr){
        $carry .= $arr["num"];
        return $carry;

    }, "") // value is "123"
    ->replace("/2/", "") // value is "13"
    ->then(function($value){
      if (empty($value)) {
        throw new \Exception("Empty value");
      }
      return $value;
    })
    ->value();
echo $res; // "13"

Accessing methods directly

<?php
use \Dsheiko\Extras\Arrays;

class Foo
{
    public $bar = "BAR";
}

$arr = Arrays::from(new Foo); // ["bar" => "BAR"]

Plain object

<?php
use \Dsheiko\Extras\Arrays;

$po = Arrays::object(["foo" => "FOO", "bar" => ["baz" => "BAZ"]]);
echo $po->foo; // FOO
echo $po->bar->baz; // BAZ
var_dump($po->bar->entries()); // [["baz", "BAZ"]]
