Distribute teams in a Schedule with php

@ragyauthorJun 24.2010 — #hello

i tried this code and it works ,but i want to show the name of each team not the numbers. this code accepts the number of teams to play and generate the schedule .

<body>

<form id="4" name="4" action="test.php" method="post">

<input type="text" id="teams" name="teams" />

<input type="submit" name="submit" value="submit" />

</form>

<?php

$teams=array ("team1","team2","team3","team4");

$n =$_POST['teams'];

if (!empty($_GET['n']) && ctype_digit($_GET['n'])) {

$n = $_GET['n'];

}

echo '<pre>' . generateRoundRobinPairings($n) . '</pre>';

function generateRoundRobinPairings($num_players) {

//do we have a positive number of players? otherwise default to 4

$num_players = ($num_players > 0) ? (int)$num_players : 0;

//set number of players to even number

$num_players = ($num_players % 2 == 0) ? $num_players : $num_players + 1;

//format for pretty alignment of pairings across rounds

$format = "%0" . ceil(log10($num_players)) . "d";

$pairing = "$format-$format ";

//set the return value

$ret = $num_players . " Player Round Robin:n-----------------------";

//print the rounds

for ($round = 1; $round < $num_players; $round++) {

$ret .= sprintf("nDay #$format : ", $round);

$players_done = array();

//print the pairings

for ($player = 1; $player < $num_players; $player++) {

if (!in_array($player, $players_done)) {

//select opponent

//$opponents= array("team")

$opponent = $round - $player;

 //echo $opponent.'<br>';
   $opponent += ($opponent < 0) ? $num_players : 1;
   //ensure opponent is not the current player
   if ($opponent != $player) {
   //choose colours
   if ($player % 2 == $opponent % 2) {
   if ($player < $opponent) {
   //player plays black
   $ret .= sprintf($pairing, $opponent, $player);
   } else {
   //player plays white
   //  $ret .= sprintf($pairing, $player, $opponent);
   }
   } else {
   if ($player < $opponent) {
   //player plays white
   $ret .= sprintf($pairing, $player, $opponent);
   } else {
   //player plays black
   $ret .= sprintf($pairing, $opponent, $player);
   }
   }
   //these players are done for this round
   $players_done[] = $player;
   $players_done[] = $opponent;
   }
   }
   }
   //print the last pairing (i.e. for the last player)
   if ($round % 2 == 0) {
   $opponent = ($round + $num_players)/ 2;
   //last player plays white
   $ret .= sprintf($pairing, $num_players, $opponent);
   } else {
   $opponent = ($round + 1) / 2;
   //last player plays black
   $ret .= sprintf($pairing, $opponent, $num_players);
   }
  }
  return $ret;

}
