PHP sort values with two table results - php

Question

I am attempting to sort results using ORDER BY DESC, but results are being sorted by foreach values:
while($row = mysqli_fetch_array($sqlgroup)){
$member_array = $row["member_array"];
if ($member_array !=""){
$memberArray = explode(",", $member_array);
$i = 0;
$cashstatsList .= '
';
foreach($memberArray as $gkey => $mvalue){
$i++;
$arraystats = "SELECT player.first_name, player.last_name, SUM(groupcash.grpcsh_earnings) AS memsum, AVG (groupcash.grpcsh_earnings) AS memavg,
SUM(groupcash.grpcsh_w) AS memcntpos, SUM(groupcash.grpcsh_l) AS memcntneg
FROM player, groupcash
WHERE (player.id = grpcsh_plrid) AND (player.id = $mvalue) AND (groupcash.grpcsh_groupid = $groupid)
AND (grpcsh_date >= '$thisyr') AND (grpcsh_date <= '$today') ORDER BY SUM(groupcash.grpcsh_earnings) DESC
";
$arraystatsResutls = mysqli_query($link, $arraystats);
if (!$arraystatsResutls){
$cashstatsList .= '
<tr>
<td>
No results available for listed dates
</td>
</tr>';
} else {
while($row = mysqli_fetch_array($arraystatsResutls)){
$memberFirstName = $row["first_name"];
$memberLastName = $row["last_name"];
$sum = $row["memsum"];
$avg = $row["memavg"];
$win = $row["memcntpos"];
$loss = $row["memcntneg"];
if ($memberFirstName == "" || $memberLastName == ""){
$sqlName = mysqli_query($link, "SELECT first_name, last_name FROM player WHERE id='$mvalue' LIMIT 1") or die ("Sorry we had a mysql error!");
while ($row = mysqli_fetch_array($sqlName)) {
$memberFirstName = $row["first_name"]; $memberLastName = $row["last_name"];
}
}
if ($sum == ""){
$sum = "0";
}
if ($avg == ""){
$avg = "0";
}
if ($win == ""){
$win = "0";
}
if ($loss == ""){
$loss = "0";
}
$cashstatsList .= '
<tr align="center">
<td>
' . $i . '
</td>
<td>
' . $memberFirstName . ' ' . $memberLastName . '
</td>
<td>
$' . $sum . '
</td>
<td>
$' . $avg . '
</td>
<td>
' . $win . '/' . $loss . '
</td>
</tr>';
}
}
}
}
}

You have to select all member of the group at once in the query so they can be "ORDER BY", here you have only results on the same member for each request so the order doesn't change anything in the order of result between member.
If $member_array is like 1,454,33,22 you can just remove the foreach and use the query :
$arraystats = "SELECT player.first_name, player.last_name, SUM(groupcash.grpcsh_earnings) AS memsum, AVG (groupcash.grpcsh_earnings) AS memavg,
SUM(groupcash.grpcsh_w) AS memcntpos, SUM(groupcash.grpcsh_l) AS memcntneg
FROM player, groupcash
WHERE (player.id = grpcsh_plrid) AND (player.id IN ($member_array)) AND (groupcash.grpcsh_groupid = $groupid)
AND (grpcsh_date >= '$thisyr') AND (grpcsh_date <= '$today') ORDER BY SUM(groupcash.grpcsh_earnings) DESC
";
So you will get all the member of the group at the same time and the ORDER BY will work.
