I have a piece of code that generates soccer/football fixtures. The idea is that for every round of fixtures, the date will be 4 days further than the last round. So round one will be 3rd may, round two will be 7th may, round three 11th may, etc.

I am not sure how to do this? The code that currently makes the fixtures are as follows:

        $totalRounds = $teams - 1;
    $matchesPerRound = $teams / 2;
    $rounds = array();
    for ($i = 0; $i < $totalRounds; $i++) {
        $rounds[$i] = array();
    }

    for ($round = 0; $round < $totalRounds; $round++) {
        for ($match = 0; $match < $matchesPerRound; $match++) {
            $home = ($round + $match) % ($teams - 1);
            $away = ($teams - 1 - $match + $round) % ($teams - 1);
            // Last team stays in the same place while the others
            // rotate around it.
            if ($match == 0) {
                $away = $teams - 1;
            }

            $rounds[$round][$match] = "$user[$home]~$team[$home]@$user[$away]~$team[$away]";
        }
    }

The teams would be the total users in the league. So if there are 8 teams, there will be 7 rounds. And i will want each round 4 days apart. And that date will be within each fixture within each round.

Any further information needed just ask! Thanks, really stuck on this
