Improve My "Round Robin Generator" Function!

- I have a list of eight teams. (e.g. Teams 1, Team 2, ..., Team 8)

- I have a list of seven weekly dates (e.g. Sep 10, Sep 17, ..., Oct 28)

- I have a list of four different times (e.g. 5:45, 6:45, 7:45, 8:30)

- I've pasted my roundRobin function below.

- I also pasted the code that I use to create the round robin (underneath the function) with the teams, dates, and times listed above.

- Running this code results in a schedule similar to one that I've attached. (Each time it is slightly different since the times are randomized.)

- What I want is for the resulting times to be more fairly distributed and spread out. For example, as you can see in the attached photo, Team #5 plays at 7:45 5 out of 7 weeks. That isn't acceptable. Also, if possible, I don't want a team to play at the same time for two consecutive weeks. For example, Team #5 again plays at 7:45 on Sep 16 and then again at 7:45 on Sep 23. I don't want that to occur.

function roundRobin(array$teams)


if (count($teams)%2!=0) {array_push($teams,"Bye");}$two=array_splice($teams,(count($teams)/2));$one=$teams;

for ($i=0;$i<count($one)+count($two)-1;$i++)


for ($j=0;$j<count($one);$j++) {$round[$i][$j]["1"]=$one[$j];$round[$i][$j]["2"]=$two[$j];}

if(count($one)+count($two)-1>2) {$s=array_splice($one,1,1);$slice=array_shift($s);array_unshift($two,$slice);array_push($one,array_pop($two));}


return $round;


$numtimes=mysql_num_rows(mysql_query("SELECT `id` FROM `times`"));

$teamsquery = mysql_query("SELECT * FROM `teams`");

while ($row = mysql_fetch_assoc($teamsquery))


if (!$list) {$list=array();array_push($list, $row['num']);}else {array_push($list, $row['num']);}}

$rounds = roundRobin($list);

foreach($rounds as $round => $games)


$date = mysql_result(mysql_query("SELECT `id` FROM `dates` ORDER BY `date` ASC LIMIT ".($round).",1"),0);

foreach ($games as $team)


$time = mysql_result(mysql_query("SELECT `id` FROM `times` WHERE ".$limitation." ORDER BY RAND() LIMIT 1"),0);

$limitation.=" AND `id`!='".$time."'";

$insert = mysql_query("INSERT INTO `schedule` VALUES (NULL, '".$date."', '".$time."', '".mres($team[1])."', '".mres($team[2])."', '');");
