In my class I have stored the ranks -- matching those in the Rank Table -- and correlating minimum scores; RANK as key and MINIMUM_SCORE as value.
When a member's score (XP) is updated (up/down) I want to test that updated score against the below array to determine if their rank needs updating too.
private $scores = array('3' => '12116', '2' => '15146', '1' => '18932',);
Using the updated score, how could I determine the correlating rank from the above array?
Everything is open to scrutiny, this is my first time creating a ranking system so I hope to get it right :)
