" games to date " ; } function getPoints($teamData){ /*This function takes an array of team data and returns a string containing the points and calculates the old two points system */ $oldpoints = $teamData["won"] * 2 + $teamData["drew"]; return $teamData["team"] ." have " . $teamData["points"] . " points under the current system " . "<br> Under two points for a win they would have " . $oldpoints ; } function getDifference($teamData){ /*This function takes an array of team data and returns a string containing the name of the team and its goal difference in the leauge */ return $teamData["team"] ." goal difference is " . $teamData["difference"] .
