I have created a fixture generator for football/ soccer games...

        $totalRounds = $teams - 1;
    $matchesPerRound = $teams / 2;
    $rounds = array();
    $roundDates = array();
    $curTime = time();

    for ($i = 1; $i <= $totalRounds; $i++) {
        $rounds[$i] = array();
        $numDays = $i * 4;
        $roundDates[$i] = strtotime("+".$numDays." days",$curTime);

    }

    foreach($roundDates as $time) {
        for ($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[$away]~$time";
            }
        }
    }

In the code, for $i = 1, i thought that if you want the first date 4 days from now, the i must be 1, so 1 * 4 = 4. If i was 0, 0 * 4 equals 0. I assume this is correct thinking?

Anyway the main question is, trying to generate the dates isn't working. When i created a fixture list for 4 users home and away, I got 12 fixtures. 10 of these had the same date on them, and the other 2 didnt have a date.

Can anyone help me with this? Thanks
