In the first version,there is that method:the variables is:
$level=the level of the adopt
$mlevel=the level of the monster.

PHP Code:

$plusexp = currentexp + 20

//Set EXP in the database

$query = "UPDATE " .$prefix."owned_adoptables SET
currentexp='".$plusexp"' WHERE aid='".$id."'";
    mysql_query($query); 


This code needs updates,and it works when is a win.
EDIT:I found a random link script in PHP.
