Funktions
=========

[](#funktions)

Funktions is a set of useful PHP functions aiming to ease your life by appending missing ones from PHP core, with a salt for functional programming. It has been heavily inspired by Ruby-ish API and augmented from real life needs from my professional use cases.

These functions are designed:

- to be immutables
- to support iterables, not only arrays
- to support all callables, not only closures
- to use generators first, because it rocks!

**WARNING!!! THIS LIBRARY IS STILL UNDER HEAVY DEVELOPMENT AND IS NOT TESTED YET**

Install
-------

[](#install)

```
composer require pyrsmk/funktions
```

Usage
-----

[](#usage)

```
use function Funktions\array_flatten;

$fruits = [
  ['strawberries', 'kiwis'],
  [
    ['oranges'],
    [
      ['lemons'],
      [
        'melons',
        ['raspberries']
      ]
    ]
  ]
];

$flatten_fruits = array_flatten($fruits);
```

### `array.php`

- `array_flatten (array $array, ?int $min_depth = null) : array` : Flatten an array by keeping an arbitrary minimum depth if necessary.
- `array_merge_recursive_unique (array ...$arrays) : array`: Contrary to `array_merge_recursive()`, it merges array by replacing values of the same key instead of appending them into a new array.
- `array_seek (array &$array, int|string $key) : void`: Move the array pointer to a specified key (mutable).
- `array_substitute (array $array, int $offset, int $length, array $replacement) : array`: Improved `array_splice()` with full string keys support when replacing.
- `glue (array $array, string $glue = '') : string`: Glue array elements together, like `implode()` but with parameters in the right order.
- `immut_array_push (array $array, ...$elements) : array`: Immutable `array_push()`.
- `immut_array_shuffle (array $array) : array`: Immutable `shuffle()`.
- `immut_array_unset (array $array, int|string $key)`: Immutable `unset()`.
- `immut_array_unshift (array $array, ...$elements) : array`: Immutable `array_unshift()`.
- `immut_arsort (array $array, int $flags = SORT_REGULAR) : array`: Immutable `arsort()`.
- `immut_asort (array $array, int $flags = SORT_REGULAR) : array`: Immutable `asort()`.
- `immut_krsort (array $array, int $flags = SORT_REGULAR) : array`: Immutable `krsort()`.
- `immut_ksort (array $array, int $flags = SORT_REGULAR) : array`: Immutable `ksort()`.
- `immut_natcasesort (array $array) : array`: Immutable `natcasesort()`.
- `immut_natsort (array $array) : array`: Immutable `natsort()`.
- `immut_rsort (array $array, int $flags = SORT_REGULAR) : array`: Immutable `rsort()`.
- `immut_sort (array $array, int $flags = SORT_REGULAR) : array`: Immutable `sort()`.
- `immut_uasort (array $array, callable $compare) : array`: Immutable `uasort()`.
- `immut_uksort (array $array, callable $compare) : array`: Immutable `uksort()`.
- `immut_usort (array $array, callable $compare) : array`: Immutable `usort()`.
- `kmax (array $array) : mixed`: Return the key of the maximum value.
- `kmin (array $array) : mixed`: Return the key of the minimum value.

### `color.php`

[](#colorphp)

- `hex2rgb (string $hex) : array`: Convert HTML to RGB color.
- `hsl2rgb (int $h, int $s, int $l) : array`: Convert HSL to RGB color.
- `hsv2rgb (int $h, int $s, int $v) : array`: Convert HSV to RGB color.
- `rgb2hex (int $r, int $g, int $b) : string`: Convert RGB to HTML color.
- `rgb2hsl (int $r, int $g, int $b) : array`: Convert RGB to HSL color.
- `rgb2hsv (int $r, int $g, int $b) : array`: Convert RGB to HSV color.

### `iterable.php`

[](#iterablephp)

- `all (iterable $iterable, callable $callable) : bool`: Return `true` when all elements match the callable's condition.
- `any (iterable $iterable, callable $callable) : bool`: Return `true` when at least one element matches the callable's condition.
- `ensure_generator ($maybe_a_generator) : Generator`: Ensure that the passed value will be a generator.
- `enumerate (iterable $iterable, ?callable $callable = null) : int`: Enumerate elements in an iterable.
- `first (iterable $iterable) : mixed`: Return the first element of an iterable. Note that the iterable's pointer will be resetted.
- `iterable_to_generator (iterable $items) : Generator`: Convert an iterable to a generator.
- `itoa (Traversable $iterator, bool $use_keys = true) : array`: Alias to `iterator_to_array()`.
- `itog (iterable $items) : Generator`: Alias to `iterable_to_generator()`.
- `last (iterable $iterable) : mixed`: Return the last element of an iterable. Note that: if the iterable is an array, then its pointer will be resetted; if the iterable is not an array, it will be converted to one, then have in mind that a complete iteration will be done before being able to get its last element.
- `map (iterable $iterable, callable $callable) : Generator`: Like `array_map()` but works on any iterable and with key/value support.
- `none (iterable $iterable, callable $callable) : bool`: Return `true` when no element has matched the callable's condition.
- `pluck (iterable $iterable, string ...$keys) : Generator`: Extract lines from an iterable based on the requested keys.
- `reduce (iterable $iterable, callable $callable, $initial = null)`: Like `array_reduce()` but works on any iterable and with key/value support.

- `select (iterable $iterable, callable $callable) : Generator`: Select items that match the callable's condition.
- `value (iterable $iterable, string $key) : mixed`: Retrieve a value from an iterable with a specified key. Note that it should be used with a hash or an array because iterating other an iterable for searching an element is not efficient at all.

### `instruction.php`

[](#instructionphp)

- `condition (bool $test, callable $truthy, callable $falsy) : mixed`: Return a value based on a test.
