PHP 按 2 个或更多值相加排序

Question

我想知道如何将 2 个值相加来排序，

我试过了，但没用..

$q = sprintf("SELECT * FROM Game ORDER BY hitpointsXp DESC + attackXp DESC + strengthXp DESC + defenceXp DESC",
          mysql_real_escape_string($user));
    $getHS = $database->query($q) or die(mysql_error());


if(mysql_num_rows($getHS) == 0){
        //Row code here
}

我这样试过，但是没用，See here

$q = sprintf("SELECT * FROM Game ORDER BY hitpointsXp DESC, attackXp DESC, strengthXp DESC, defenceXp DESC",

Answer 1

你试过这个吗，

SELECT *, (hitpointsXp + attackXp + strengthXp + defenceXp) as TotalXp FROM Game ORDER BY TotalXp DESC

希望对您有所帮助。
