Round Robin Tournament Scheduler
Here's a snippet I wrote for a project that I thought might come in handy for someone else. It generates a schedule for a round robin tournament. I found some other snippets to do this, but I found them overly complicated or lacking in other ways.
Here's an example of what this code does:
< ?php $players = range(1, 8); echo 'Original List: ' . PHP_EOL; print_r($players); echo PHP_EOL; echo 'Round Robin Schedule: ' . PHP_EOL; print_r(generateRRSchedule($players)); ?>
Output:
Original List:
Array
(
[0] => 1
[1] => 2
[2] => 3
[3] => 4
[4] => 5
[5] => 6
[6] => 7
[7] => 8
)
Round Robin Schedule:
Array
(
[0] => Array
(
[0] => Array
(
[0] => 1
[1] => 8
)
[1] => Array
(
[0] => 2
[1] => 7
)
[2] => Array
(
[0] => 3
[1] => 6
)
[3] => Array
(
[0] => 4
[1] => 5
)
)
