Optimizing just for memory here doesn't make sense. That's not something which will be called often. When you read the first post, if he doesn't specify the optimizating edge is because he asks about how to organize better his code, which can be lead to a better usage of memory for sure. What I mean is your tip won't help him, you make the code more difficult for a trivial gain. (But for sure, it can be useful for specific case)

Then how about looking more structural by using enums.

PHP Code:

enum _:COUNTERS
{
  cntr_nemesis,
  cntr_multimod,
  cntr_swarmmod,
  cntr_survivor,
  cntr_plaguemod,
  cntr_synapsismod,
  cntr_armagedonmod
}

new counters[33][COUNTERS];

counters[id][cntr_nemesis]++;
