Looking to change order of stats shown - php

Question

I tried combining as suggested in a previous link but Im still getting a error. I am fairly new to php so that is why i have two querys.
Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource in /home/vhockey/public_html/vhatest/connect.php on line 88
The table is "season12" and the table is "p"
Here is my connect.php file except server info...
function index_team_stats($subconference) {
$return = array();
$query = "SELECT id, teamname, teamnameseason, teamabr
FROM teams
WHERE subconference = '" . $subconference . "'
ORDER BY teamnameseason";
$teams = result_array($query);
foreach ($teams as $team)
{
$query = "SELECT gp, w, l, ol, p
FROM season12
WHERE team = '" . $team['teamnameseason'] . "'
ORDER BY p DESC
LIMIT 0,20'; ";
$results = result_array($query);
if ($results)
{
$results[0]['team'] = str_replace($team['teamnameseason'], '', $team['teamname']);
$results[0]['teamabr'] = $team['teamabr'];
$results[0]['teamid'] = $team['id'];
$return[] = $results[0];
}
}
return $return;
}
function get_team_name($teamnameseason) {
$query = "SELECT teamname FROM teams WHERE teamnameseason = '" . $teamnameseason . "'";
$row = mysql_fetch_row(mysql_query($query));
return str_replace($teamnameseason, '', $row[0]);
}
function result_array($query) {
$results = mysql_query($query) or die("error on: " . $query . " saying: " . mysql_error());
$return = array();
while ($row = mysql_fetch_assoc($results)) {
$return[] = $row;
}
return $return;
}
Here is an image of the info ![All info sorted by team PTS from highest to lowest
Should show Penguins, FLyers, Islanders, Rangers, Devils..

Answer 1

Use a JOIN. An example is below. You may need to tweak based on your specific needs.
SELECT teams.id, teams.teamname, teams.teamnameseason, teams.teamabr, season12.gp,
season12.w, season12.l, season12.ol, season12.p
FROM teams, season12
INNER JOIN season12
ON teams.teamname=season12.team
WHERE teams.subconference = '$subconference'
ORDER BY season12.p
LIMIT 0,20
Please note this code is not tested and may require modification.

Answer 2

You can use php sort function http://php.net/usort
$callback = new function ($el1, $el2) {
if ($el1['points'] == $el2['points']) {
return 0;
}
return ($el1['points'] < $el2['points']) ? -1 : 1;
}
$sorted_result = usort($results, $callback);
