Question

Hey, my problem is as follows, I am trying to create code where a set of sporting fixtures are created with dates on. Say I have 8 teams, with 7 rounds of fixtures.

I have generated the fixtures, but want to add a date generation on them. So if i had 7 rounds, I would put 28 days and it would make each round 4 days from now, 8 days from now, etc.

What would be the best way to go about doing this? Thanks

This should do what you want and allows for an uneven number of teams. Dates might not be perfect because of the rounding down:

    $teams = array("TEAM A","TEAM B","TEAM C","TEAM D","TEAM E", "TEAM F","TEAM G","TEAM H","TEAM I");
    $days = 28;
    $rounds = count($teams) -1;

    //Number of Days Between Fixtures
    $daysBetweenFixtures = floor($days / $rounds);


    $fixtures = array();

    for($i =0; $i < count($teams); $i++) {
        //Calculate Date of this round of fixtures
        $date  = date("D d M Y",mktime(0, 0, 0, date("m")  , date("d")+ ($i * $daysBetweenFixtures) , date("Y")));

        $hasFixtureToday = array();

        for($j=$i; $j<$i+count($teams);  $j=$j+2) {
            $homeTeam = $teams[$j % count($teams)];         
            $awayTeam = $teams[($j+1) % count($teams)];

            if(!in_array($homeTeam,$hasFixtureToday) && !in_array($awayTeam,$hasFixtureToday)) {
                $fixtures[$date][] = "{$homeTeam} vs {$awayTeam}";
                $hasFixtureToday[] = $homeTeam;
                $hasFixtureToday[] = $awayTeam;
            }
        }
    }
    print_r($fixtures);
