Tournament System - psuedo code

[Kemik]

Hello all,

 

I’m building a tournament system and I’m going through the planning stages, specifically making the psuedo code.

 

I’m trying to think how I would take a list of players, add a number of passes if there are spaces left (total spaces - number of users signed up) and then randomise who each user plays against.

 

The system is using user_ids to identify users.

 

So, on click of “Make fixtures” the following occurs:

 

1. Get $maxusers and $nosignedup.

2. $passes = $nosignedup - $maxusers.

3. Get array of users ($users [user_id])

4. A loop to add a user with the user_id of -1 for each pass to $users array.

 

Here’s where I’m stuck. I need to randomise the user_id in the array and then some how make fixtures for the tournament. E.g. if the tournament has max users of 8 it will make 4 fixtures.

 

Any ideas would be appreciated.

try using the

shuffle($user_id_array) 

function...

Oh thanks! Never heard of that function.

 

Should be easy enough to make the fixtures from there.

 

5. Use shuffle function.

6. $nofixtures = $maxusers / 2

7. Loop for $nofixtures create a new fixture with incremental $fixture_id, $userone = incremental user, $usertwo = next user in the array.

 

I'm going to do a bit more searching for the loops so I don't have much experience with loops and getting incremental information so feel free to post suggestions.
