[PHP] Re: randomize etc?
split should work fine... Just do something like: $teamMembersArray = split( ,;, $textarea); That will give you an array of the team members. Of course I'm assuming that their names don't include spaces and that you'll separate them with either a space, comma, or semi-colon. And you'll want to get rid of any newlines in $textarea as well. -philip On Thu, 1 Aug 2002, Hawk wrote: I'm trying to make a small script that I can use for randomizing teams and stuff, I have one field where I enter how many teams, one for how many in each team, and a textarea to write down all the players in. This is where my brain stopped working, first I was thinking about using split, but I don't know how when there isn't a predefined number of variables to split it into, how do I do this? and when I have separated them into variables, how do I put them into arrays? or maybe that's not a good way to do it? I don't know, and the heat in my room is killing me, can't think clearly :) Håkan -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

This might be a bit more helpful ;) There are several way to do it, this
is just one. Unoptimised, aimed at readability.
?php
// Split $items equally among $items
function randGroup($items, $groups) {
// Init
$return = array();
$cnt = 0;
// Shuffle
srand ((float)microtime()*100);
shuffle ($items);
// Divide up
while (sizeof($items)) {
$return[$cnt++] = array_pop($items);
if ($cnt = $groups) $cnt = 0;
}
// Return
return $return;
}
// Replace these with the items you want, and specifiy 4 groups
$items = array(1,2,3,4,5,6,7,8,9,10,11,12,13,14);
$result = randGroup($items, 4);
echo pre; print_r($result); echo /pre;
