SQL Select count multiple columns and sort - php

Question

So I'm trying to sort from highest prestiges and then highest experience (xp)
public function getRank($user, $skill, $mode) {
$skill2 = strtolower($skill)."_xp";
$skill3 = strtolower($skill)."_prestiges";
$stmt = $this->conn->prepare("SELECT (
SELECT COUNT(*) FROM hs_users WHERE mode = :mode AND (
$skill3 >= u.$skill3 AND $skill2 >= u.$skill2
)
) AS rank
FROM hs_users u
WHERE username = :user AND mode = :mode2
LIMIT 1");
$stmt->bindParam(":user", $user);
$stmt->bindParam(":mode", $mode);
$stmt->bindParam(":mode2", $mode);
$stmt->execute();
return $stmt->fetchColumn();
}
At the moment I'm getting duplicate rankings, two people are rank 1.
For example
if someone is prestige 1 and 3,000,000 experience and then someone is prestige 0 and 4,000,000 experience they achieve the same ranking, as to the second person is suppose to be rank 2.
I've been trying ORDER BY but it doesn't seem to be working. I'm not too experienced with SQL queries, if you have any pointers or could help me that'd be great.

Answer 1

If prestige is the primary ranking attribute:
$stmt = $this->conn->prepare("SELECT id, $skill3, $skill2
FROM hs_users
WHERE username = :user
AND mode = :mode
");
$stmt->bindParam(":user",$user);
$stmt->bindParam(":mode",$mode);
if($stmt->execute()){
$user = $stmt->fetch(PDO::FETCH_ASSOC);// get the users id, prestige and experience level
}
$higherPrestiges = array();
$stmt = $this->conn->prepare("SELECT id
FROM hs_users
WHERE $skill3 >= :skill3
AND mode = :mode");
$stmt->bindParam(":skill3",$user[$skill3]);
$stmt->bindParam(":mode",$mode);
if($stmt->execute()){
while($row = $stmt->fetch(PDO::FETCH_COLUMN)){ //get all users that have higher prestige
$higherPrestiges[$row] = $row;
}
}
if(count($higherPrestiges) > 0){
$higherPrestiges_implode = implode(",",$higherPrestiges);
}else{
$higherPrestiges_implode = "0";
}
$lowerExperiences = array();
$stmt = $this->conn->prepare("SELECT id
FROM hs_users
WHERE $skill3 = :skill3
AND $skill2 < :skill2
AND mode = :mode");
$stmt->bindParam(":skill2",$user[$skill2]);
$stmt->bindParam(":skill3",$user[$skill3]);
$stmt->bindParam(":mode",$mode);
if($stmt->execute()){
while($row = $stmt->fetch(PDO::FETCH_COLUMN)){//get users with lower experience with the same prestige
$lowerExperiences[$row] = $row;
}
}
if(count($lowerExperiences) > 0){
$lowerExperiences_implode = implode(",",$lowerExperiences);
}else{
$lowerExperiences_implode = "0";
}
$stmt = $this->conn->prepare("SELECT COUNT(id)
FROM hs_users
WHERE mode = :mode
AND id IN(".$higherPrestiges_implode.")
AND id NOT IN(".$lowerExperiences_implode.")");
$stmt->bindParam(":mode",$mode);
if($stmt->execute()){
$rank = $stmt->fetch(PDO::FETCH_COLUMN);//get number of users that have higher or equal prestige and exclude the ones with lower experience
}
Just replace references to "id" in the queries with the column name for primary keys in your table
I do realize the last 3 queries can be combined with subqueries in the IN clause, but this should make it easier to understand
