我正在创建一个跟踪高尔夫比分并将其返回给用户的网站。每一轮，玩家放入他们的分数，然后我想显示玩家拥有多少分，小鸟，转向架等。每个球场都有洞的值。我需要取得玩家的分数，从par值中算出-1,0，+ 1，+ 2等。之后，我需要弄清楚整个回合中有多少小鸟，草坪，转向架等，并将它们列在桌子上。
有人知道这样做的方法吗？我一直坐在这里思考这个问题已有一段时间了，我无法想到如何做到这一点。
以下是我的询问：
$user = $_GET['user_id'];
$get_player = "SELECT *
FROM users
WHERE user_id = '$user'";
$run_player = mysqli_query($con, $get_player);
$row_player = mysqli_fetch_array($run_player);
$get_rounds = "SELECT *
FROM user_rounds
INNER JOIN courses
ON user_rounds.course_name=courses.course_name
WHERE user_id = '".$row_player['user_id']."'";
$run_rounds = mysqli_query($con, $get_rounds);
while($row_rounds = mysqli_fetch_array($run_rounds)) {
然后从这里开始我正在努力为所有这些做数学。我的表格中存储了每个分数以及他们所演奏的课程名称;所以这两个表匹配得很好。
任何帮助将不胜感激!!

所以第一个将是小鸟等，我正在寻找的是能够将所有的小腿，小鸟，转向架等组合在一起，然后在所有轮次中将它们全部放在一起已经玩过了。
