-- Create table at startup:
g_Players = {}

function OnWorldStarted(World) -- Hook that gets called when the worlds are initialized
 g_Players[World:GetName()] = {}
end

-- Add to table:
table.insert(g_Players[cPlayer:GetWorld():GetName()], cPlayer:GetName())

-- Go through all the values. Assuming you need it every tick:
function OnWorldTick(World, TimeDelta)
 for Idx, PlayerName in ipairs(g_Players[World:GetName()])
  World:DoWithPlayer(PlayerName, function(Player)
   -- Do awesome stuff here
  end)
