Where are you stuck exactly?

You will have to modify this code to match what you want but this gives you a starting point anyway:

 

<table width=600 align=center>
<tr>

/*

    // Find out how many teams we want fixtures for.
    if (!isset($_GET['teams'])) {
        print get_form();
        exit;
    }
    $teams = $_GET['teams'];
    $weeks = $_GET['weeks'];
    $startdate = $_GET['startdate'];

    // If odd number of teams add a "ghost".
    $ghost = false;
    if ($teams % 2 == 1) {
        $teams++;
        $ghost = true;
    }

    // Generate the fixtures using the cyclic algorithm.
    $totalRounds = $weeks;
    $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][$match] = ($home + 1) . " v " . ($away + 1);
        }
    }

/*   // Interleave so that home and away games are fairly evenly dispersed.
    $interleaved = array();
    for ($i = 0; $i < $totalRounds; $i++) {
        $interleaved[$i] = array();
    }

    $evn = 0;
    $odd = ($teams / 2);
    for ($i = 0; $i < sizeof($rounds); $i++) {

    }    */

    // Display the fixtures

        print "<p>Round " . ($i + 1) . "</p>\n";
