PHP Code:

  gainExperience(levelName, amountGain);
    //gainExperience("stength", 45)
    // Gives the player 45 exp for a strength level. It also creates a stat for overall experience gained. This stat is saved as "clientr.stat_exp-main".

  expNeeded(levelName);
    //expNeeded("strength");
    // Returns how much EXP is needed for gaining a level.

  gatherExperience(levelName);
    //gatherExperience("strength");
    // How much experience the player currently has in that level. 
  
  gatherLevel(levelName);
    //gatherLevel("strength");
    // Returns the players current level
