一个简单的 PHP 积分计算代码示例

// 定义积分规则
$rules = [
  "login" => 10, // 每次登录获得10分
  "share" => 5, // 每次分享获得5分
  "comment" => 2 // 每次评论获得2分
];

// 获取用户当前积分
function getPoints($userId) {
  if (isset($_SESSION["points"][$userId])) {
    return $_SESSION["points"][$userId];
  } else {
    $_SESSION["points"][$userId] = 0;
    return 0;
  }
}

// 计算用户获得积分
function calculatePoints($userId, $action) {
  global $rules;
  $points = getPoints($userId);
  $pointsToAdd = $rules[$action];
  if ($pointsToAdd) {
    $totalPoints = $points + $pointsToAdd;
    $_SESSION["points"][$userId] = $totalPoints;
    return $totalPoints;
  } else {
    return $points;
  }
}
