README

This package allows you to generate round robin tournament matchups based on the Berger tables.

Usage

use Philicevic\Berger\Services\RoundRobin;


$teams = ['A', 'B', 'C', 'D'];
$rounds = RoundRobin::makeFromTeams($teams);

// 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

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

Every fixture has two properties.

$fixture->home
$fixture->away

Both contain just the name of the team.
