$hpAccumulator -= SOME_VALUE need to the same value as if($hpAccumulator > SOME_VALUE)

Try thinking about it. Say for example that exactly 30 milliseconds elapses between each update. Trace for yourself what the value of $hpAccumulator will be each time through.

This updates the variable. The variable '$ir['hp']' represents how many hitpoints the player has. (I'm assuming '$ir' is the data for the current player.) The database is for remembering data between plays of the game. Variables keep track of things while the game is running.
