random

Okay im trying to do something that seems very hard that i cant even think of how to do it as of right now.  Okay.

I have 80 teams in a league i created im trying to run a script to make each team get matched up to 8 random teams

how could i go about doing this

[desithugg]

$team['1'] = "team 1";
$team['2'] = "team 2";
$how_many_teams = 8;
$i = "0";
foreach($team as $team2)
{
for($team3 = $team2; $i =0; $i >= $how_many_teams; $i++)
{
$rand_team = rand(1,80);
echo $team3." with team";
}
}

umm didn't really get what you meant but try this

make an array containing all 80 teams, then do a foreach loop that will do a random 8 different times.

Everytime it finds a match, add it to a new array, check to make sure it isn't already in that array by using

in_array(). if its not append it to the end of the array. If it is in the array, make another search of the original

array. Keep doing this until you have run through the list 80 times.

I believe the follow code does what you want:

<?php
$teams = range(1,80);
$selections = array();
for($j=0;$j<80;$j++) {
$tmp = array();
for($i=1;$i<9;$i++) {
	$tst = $teams[array_rand($teams)];
	while($tst != $teams[$j] && in_array($tst,$tmp)) $tst = $teams[array_rand($teams)];
	$tmp[$i] = $tst;
}
sort($tmp);
$selections[$j] = implode(',',$tmp);
}
echo '<pre>' . print_r($selections,true) . '</pre>';
?>

<?php
//I didn't want to make any array... So i made it with a for loop.
//It uses numbers.
$array = array();
for($i = 1; $i < 81; $i++){
array_push($array, "$i");
}

foreach($array as $val){
$rand = array_rand($array, ;
echo $val. ' > '. $rand[0].'<br>';
echo $val. ' > '. $rand[1].'<br>';
echo $val. ' > '. $rand[2].'<br>';
echo $val. ' > '. $rand[3].'<br>';
echo $val. ' > '. $rand[4].'<br>';
echo $val. ' > '. $rand[5].'<br>';
echo $val. ' > '. $rand[6].'<br>';
echo $val. ' > '. $rand[7].'<br>';
}

?>
