__++====Runescape Highscorescript 1.0====++__
This class gets every lvl 30+ stat from any player, it can check level, exp and place in highscores.
I also build in a function to check how much exp someone is from a certain level.

Getskill function($player,$skill,$mode)
$player = The runescape name of the player you want the stat from
$skill = The skill you want the stat from
$mode = 0 or empty to get level, 1 to get exp, 2 to get place in highscores

Expleft function
$currentexp = the current exp of the player
$goal = the lvl you want to calculate for how much exp it is from current amount of exp.

If you have any questions, mail me: t e u n e b o o n [@] g m a i l {dot} com
