modded reguser help

[ZeroComp]

ok so I have modded my reguser.php to fit faction wars' needs and I need a little bit of help on part of it. I am wondering how to piece out a couple lines of code that will put the player in a random faction, I plan on building on that piece of code later on to put players in a faction with the least amount of players to make it fair

Make an array of the different factions or pull it from your database or however you do it..
Then make php generate a random number between the length of the array and 0.

Code: Select all

$factions = array( 'gays', 'fags', 'homos', 'queers', 'emos' );

$number = rand(0, (count($factions)-1)); // -1 because the first key is of course 0  and not 1

echo "<select name=\"factions\">\n";

foreach( $factions as $key => $value )
{
    echo "<option". ( $number == $key ? " selected=\"selected\"" : '' )  .">". $value ."</option>\n";
}
echo "</select>";
