Berger Tables for PHP
=====================

[](#berger-tables-for-php)

This package allows you to generate round robin tournament matchups based on the [Berger tables](https://en.wikipedia.org/wiki/Round-robin_tournament#Berger_tables).

Usage
-----

[](#usage)

```
use Philicevic\Berger\Services\RoundRobin;

// this creates 6 rounds where teams play each other twice
$teams = ['A', 'B', 'C', 'D'];
$matchesAgainstEachOther = 2;
$rounds = RoundRobin::makeFromTeams($teams, $matchesAgainstEachOther);

// or use it step by step

$teams = ['A', 'B', 'C', 'D'];
$rr = RoundRobin::create();
$rr->setTeams($teams);
$rounds = $rr->make();

```

`$rounds` will be an array of `Round` objects.

### Round

[](#round)

```
foreach ($rounds as $round) {
    // get array of fixtures
    $round->fixtures;

    // get number of round
    $round->number;

    // add fixture to round
    $round->addFixture($fixture);

    // remove fixture from round by index
    $round->removeFixture($index);

    // format round as array
    $round->toArray();
}

// $round->toArray() will return something like this
[
    [
        [
            'home' => 'A',
            'away' => 'C',
            'round' => 1,
        ],
        [
            'home' => 'B',
            'away' => 'D',
            'round' => 1,
        ],
    ],
    [
        [
            'home' => 'C',
            'away' => 'B',
            'round' => 2,
        ],
        [
            'home' => 'D',
            'away' => 'A',
            'round' => 2,
        ],
    ],
    [
        [
            'home' => 'A',
            'away' => 'B',
            'round' => 3,
        ],
        [
            'home' => 'C',
            'away' => 'D',
            'round' => 3,
        ],
    ],
]

```

### Fixture

[](#fixture)

Every fixture has two properties.

```
$fixture->home
$fixture->away

```

Both contain just the name of the team.

You could also access the teams via the `getTeams` method.

```
// returns ["Team A", "Team B"]
$fixture->getTeams()

```

If you want to swap the places of the teams for a fixture you can also do that.

```
$fixture->swapTeams()

```
