How can I display rank to leaderboard from score - php

Question

I'm trying to create a leaderboard using a score table from Mysql.
I only use "name" and "score" from my score table.
I can display my leaderboard ordered by best score but can't display the rank with it.
Here is my php file to get datas:
// Connect to server and select database.
$con = mysqli_connect($host, $db_username, $db_password, $db_name);
// Retrieve data from database
$sql = "SELECT *
FROM scores
ORDER BY score DESC
LIMIT 10"; // The 'LIMIT 10' part will only read 10 scores. Feel free to change this value
$result = mysqli_query($con, $sql);
// Start looping rows in mysql database.
while($rows = mysqli_fetch_array($result)){
echo $rows['name'] . "|" . $rows['score'] . "|";
// close while loop
}
// close MySQL connection
mysqli_close($con);
?>
I guess I probably need to have something like this in the end:
while($rows = mysqli_fetch_array($result)){
echo $rows['rank'] . "|" . $rows['name'] . "|" . $rows['score'] . "|";
But can't manage to get it properly…
The result should be displayed like:
<br/> Mardoch 49507
<br/> Gunthylapointe 49504
What am I doing wrong?

Answer 1

Do you want window functions?
select rank() over(order by score desc) rn, s.*
from scores
order by score desc
This adds another column to the resultset, called rn, that contains the rank of each row, ordered by descending score.

Answer 2

Well, I change a bit my code and added this:
// Retrieve data from database
$sql = "SELECT *
FROM scores
ORDER BY score DESC";
//LIMIT 10"; // The 'LIMIT 10' part will only read 10 scores. Feel free to change this value
$result = mysqli_query($con, $sql);
$i = 0;
// Start looping rows in mysql database.
while($rows = mysqli_fetch_array($result)){
$i++;
echo ($i) . "|" . $rows['name'] . "|" . $rows['score'] . "|";
// close while loop
}
It's work a bit better but it stop my leaderboard at a moment and display a lot of 0 after:
screen capture
Seems the problem is because the next score is exactly the same as the previous…So it breaks here
