How to calculate rank of the player with most money? - php

Question

I am building a leaderboard which is built by joining two different databases, the most important is the wallet column which is what I'll use to rank the players. I need to add a column ranked from the player with most money to least amount of money. What is the best way to do this?
$result = mysqli_query($conn, "SELECT * FROM darkrp_player inner join playerinformation on (darkrp_player.uid = playerinformation.uid)");

Answer 1

Basically, you need to order by on your wallet column to short for showing most money to least amount of money of the user i.e DESC ordering. But if you want to get the rank number value of each user also apart from ordering you can do it this way with ROW_NUMBER() window function
SELECT *, rank FROM (
SELECT *, ROW_NUMBER() OVER (ORDER BY wallet DESC) as rank
FROM darkrp_player INNER JOIN playerinformation ON (darkrp_player.uid = playerinformation.uid)
) t
Expected Output: on $result variable
id other........columns wallet rank
1111 xyz............abc 100 1
2222 xyz............abc 90 2
3333 xyz............abc 80 3

Answer 2

alright these work! here's my code for anyone that might across something similar
<table class="table" data-order='[[ 0, "asc" ]]'>
<thead>
<tr>
<th>Place</th>
<th>Avatar</th>
<th>Name</th>
<th>Salary</th>
<th>Wallet</th>
</tr>
</thead>
<tbody>
<?php
$conn = mysqli_connect("bla bla bla");
$result = mysqli_query($conn, "SELECT * FROM darkrp_player inner join playerinformation on (darkrp_player.uid = playerinformation.uid) ORDER BY wallet DESC");
$rank = 1;
while ($row = mysqli_fetch_assoc($result)):
?>
<?php
$steamid2 = $row['steamID'];
$slice = substr($steamid2, strpos($steamid2, ":") + 1);
$n = substr($slice, 0, 1);
$x = substr($slice, strpos($slice, ":") + 1);
$steamid64 = 76561197960265728 + 2 * $x + $n;
$json = file_get_contents('http://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002/?key=keykeykeykeykeyk&steamids='.$steamid64.'');
$parsed = json_decode($json);
?>
<tr id="rank<?php echo $rank++; ?>">
<td><?php echo $rank - 1; ?></td>
<td><?php foreach($parsed->response->players as $player){
echo "<img src='" . $player->avatarmedium . "'>";
} ?></td>
<td><?php foreach($parsed->response->players as $player){
echo "" . $player->personaname . "";
} ?></td>
<td><?php echo $row['salary']; ?></td>
<td><?php echo $row['wallet']; ?></td>
<?php endwhile; ?>
</tr>
</tbody>
