What are some considerations when implementing a points-based system in PHP for user interactions?

When implementing a points-based system in PHP for user interactions, it's important to consider security measures to prevent manipulation of points values by users. One way to address this is by using server-side validation and verification of points transactions to ensure they are legitimate. Additionally, you may want to implement logging and auditing features to track points changes for accountability purposes. 

// Example of adding points to a user's account
function addPointsToUser($userId, $pointsToAdd) {
    // Perform server-side validation to ensure pointsToAdd is a positive integer
    if($pointsToAdd > 0 && is_int($pointsToAdd)) {
        // Add points to user's account
        // Implement logging and auditing here
        $currentPoints = getCurrentPoints($userId);
        $newPoints = $currentPoints + $pointsToAdd;
        updatePoints($userId, $newPoints);
        return true;
    } else {
        return false;
    }
}
