Question

I want to ask if is there any faster method how to make this query? Actually it takes about 100 seconds to finish. I have about 10 000 000 (1 GB) rows in a table. This is the statistics generating script.

This is the query:

  $results=mysql_query("SELECT * FROM hawkeye WHERE player_id='".$playerID."'") or die("MYSQL ERROR: ".mysql_error());

And then the php code:

  $row = mysql_fetch_array($results)
  if($row["action"] == 4){$commandcount++;}
  else if($row["action"] == 3){$chatcount++;}
  else if($row["action"] == 1){$placedcount++;}
  else if($row["action"] == 0){$breakcount++;}
  else if($row["action"] == 5){$joincount++;}
  else if($row["action"] == 6){$quitcount++;}
  else if($row["action"] == 7){$qteleportcount++;}
  else if($row["action"] == 12){$pvpdeathcount++;}
  else if($row["action"] == 21){$mobkillcount++;}
  else if($row["action"] == 22){$otherdeathcount++;}
  else {}

Thanks for answers!

Use MYSQL to do the math for you. It’s faster then PHP:

SELECT COUNT(*) AS action_count
     , action
FROM hawkeye 
WHERE player_id='".$playerID."'"
GROUP BY action

while ($row = mysql_fetch_assoc($result))
{
    echo $row['action'] . ': ' . $row['action_count'] . "<br>" . PHP_EOL;
}
