Installation

You can use composer to install this extension.

Just run:

$ composer require dimaskao/sorter

How to use

General

At first include this library classes:

require_once __DIR__ . '/XXXXX/vendor/autoload.php';

use Dimaskao\Sorter\Sorter //required class

use Dimaskao\Sorter\NullSorter; //|\
use Dimaskao\Sorter\SortASC;    //|- Choose what you need
use Dimaskao\Sorter\SortDESC;   //|/

Where XXXXX path to library root folder.

If you want to sort array create Sorter object and pass SortASC or SortDESC object.

$sorter = new Sorter(new SortASC());

Then use ->sort() method and pass an array to it. This method will return a sorted array.

$sorter->sort($array);

This library use Strategy patterns so you can cheng sorting method by -setSorter(). Just pass it a new sort object.

$sorter = new Sorter(new SortDESC());

$sorter->setSorter(new SortASC());

NullSorter

For debugging you can use NullSorter().

$sorter->setSorter(new SortASC());//this will sort array
$sorter->setSorter(new NullSorter());//this would not sort array
$b = $sorter->sort($arr);

Library extension

If you would add new formats of sorting, you should create your own class which implements SorterInterface.php.

require_once __DIR__ . '/vendor/autoload.php';

use Dimaskao\Sorter\SorterInterface;

class YourFormat implements SorterInterface {

}

Example

Let's see how it works.

require_once __DIR__ . 'vendor/autoload.php';

use Dimaskao\Sorter\NullSorter;
use Dimaskao\Sorter\SortASC;
use Dimaskao\Sorter\SortDESC;
use Dimaskao\Sorter\Sorter;

$arr = [9, 0, 1, 5, 77, -5];

$sorter = new Sorter(new SortDESC());
$a = $sorter->sort($arr);

\print_r($a);

$sorter->setSorter(new SortASC());
$b = $sorter->sort($arr);

\print_r($b);

$sorter->setSorter(new SortASC());
$sorter->setSorter(new NullSorter());
$b = $sorter->sort($arr);

\print_r($b);

As a result, we get.

    [4] => 77
    [0] => 9
    [3] => 5
    [2] => 1
    [1] => 0
