I have been trying to find something about this topic and I can't seem to find anything, there were a few questions on here but they didn't work for my particular project.
I asked a similar question about updating the table but its not going to work for what I actually want here is the list of result.
--------------------------------------------------------
|id | hometeam |goalsfor|goalsagainst| awayteam |
--------------------------------------------------------
| 1 |Inter Milan | 3 | 1 | FC Barcelona |
--------------------------------------------------------
| 2 |FC Barcelona | 1 | 0 | Inter Milan |
--------------------------------------------------------
| 3 |Inter Milan | 4 | 0 | AC Milan |
--------------------------------------------------------
| 4 |AC Milan | 0 | 2 | Inter Milan |
--------------------------------------------------------
| 5 |Real Madrid | 2 | 0 | AC Milan |
--------------------------------------------------------
| 6 |AC Milan | 2 | 2 | Real Madrid |
--------------------------------------------------------
| 7 |FC Barcelona | 2 | 2 | AC Milan |
--------------------------------------------------------
| 8 |Real Madrid | 2 | 0 | Inter Milan |
--------------------------------------------------------
| 9 |Inter Milan | 3 | 1 | Real Madrid |
--------------------------------------------------------
| 10 |FC Barcelona | 2 | 0 | Real Madrid |
--------------------------------------------------------
| 11 |Real Madrid | 1 | 1 | FC Barcelona |

Basically I want to be able to create a standings table ranking the teams in order, I want to present this table on the fly and not put it into the database
Pos Team Pld W D L F A GD Pts
1 FC Barcelona 5 2 3 0 8 5 3 9
2 Inter Milan 6 2 2 2 11 10 1 8
3 Real Madrid 6 2 2 2 8 8 0 8
4 AC Milan 5 0 3 2 8 12 -4 3
POS=Position W=won D=Draw L=Loss F=Goals scored For A=Goals scored against GD=Goals difference Pts=Points
I think the most efficient way to do this would be to assign wins, draws and losses, sum the goals scored and goals scored against and when echoing out the data - calculate the total number of games played and the points.
But how would I assign wins draws or losses? And calculate the goals scored and goals against?

First union the scores table together swapping the hometeam with the awayteam and swapping the goal counts. This gives you some source data that is easily aggregated and the query to generate the score card is something like this:
select
team,
count(*) played,
count(case when goalsfor > goalsagainst then 1 end) wins,
count(case when goalsagainst> goalsfor then 1 end) lost,
count(case when goalsfor = goalsagainst then 1 end) draws,
sum(goalsfor) goalsfor,
sum(goalsagainst) goalsagainst,
sum(goalsfor) - sum(goalsagainst) goal_diff,
sum(
case when goalsfor > goalsagainst then 3 else 0 end
+ case when goalsfor = goalsagainst then 1 else 0 end
) score
from (
select hometeam team, goalsfor, goalsagainst from scores
union all
select awayteam, goalsagainst, goalsfor from scores
) a
group by team
order by score desc, goal_diff desc;
// connection stuff
$sql = 'select * from matchesTable';
$result = mysql_query($sql)
$standings = array ();
$standingTemplate = array ('matches' => 0, 'wins' => 0, 'draws' => 0, 'losses' => 0, 'goalsfor' => 0, 'goalsagainst' => 0, 'goalsdiff' => 0, 'points' => 0);
while ($row = mysql_fetch_assoc($result))
{
handleMatch($row['hometeam'], $row['goalsfor'], $row['goalsagainst']);
handleMatch($row['awayteam'], $row['goalsfor'], $row['goalsagainst']);
print_r( usort(standings, 'comparePoints') ); // up to you to format the output as you like
}
function handleMatch($team, $goalsfor, $goalsagainst)
{
global $standings, $standingTemplate;
if ($goalsfor > $goalsagainst)
{
$points = 3;
$win = 1;
$draw = 0;
$loss = 0;
}
elsif ($goalsfor == $goalsagainst)
{
$points = 1;
$win = 0;
$draw = 1;
$loss = 0;
}
else
{
$points = 0
$win = 0;
$draw = 0;
$loss = 1;
}
if ( empty($standings[$team]) )$standing = $standingTemplate;
else $standing = $standings[$team];
$standing['matches']++;
$standing['wins'] += $win;
$standing['draws'] += $draw;
$standing['losses'] += $loss;
$standing['goalsfor'] += $goalsfor;
$standing['goalsagainst'] += $goalsagainst;
$standing['goalsdiff'] += $goalsfor - $goalsagainst;
$standing['points'] += $points;
$standings[$team] = $standing;
}
function comparePoints($a, $b)
{
if ($a['points'] == $b['points'])
{
if ($a['goalsdiff'] == $b['goalsdiff']) return 0;
return ($a['goalsdiff'] < $b['goalsdiff']) ? 1 : -1 ;
}
return ($a['points'] < $b['points']) ? 1 : -1 ;
}
NOTES: I didn't test it and all, might be little bug (some $ or ; missing).

Recently I had to make quite more extended version of datatable. Although it is based on my own schema, but it maybe useful for someone (it is based on previous a'r answer):
SELECT
team_id team_id,
t.name team_name,
t.country country,
count(*) matches,
SUM(scored) scored_total,
SUM(conceided) conceided_total,
count(CASE WHEN scored > conceided
THEN 1 END) wins,
count(CASE WHEN scored = conceided
THEN 1 END) draws,
count(CASE WHEN scored < conceided
THEN 1 END) lost,
sum(scored) - sum(conceided) balance,
sum(
CASE WHEN scored > conceided
THEN 3
ELSE 0 END
+ CASE WHEN scored = conceided
THEN 1
ELSE 0 END) points,
count(CASE WHEN place = 'home'
THEN 1 END) home_matches,
count(CASE WHEN place = 'home' AND scored > conceided
THEN 1 END) home_wins,
count(CASE WHEN place = 'home' AND scored = conceided
THEN 1 END) home_draws,
count(CASE WHEN place = 'home' AND scored < conceided
THEN 1 END) home_lost,
SUM(CASE WHEN place = 'home'
THEN scored
ELSE 0 END) home_scored,
SUM(CASE WHEN place = 'home'
THEN conceided
ELSE 0 END) home_conceided,
count(CASE WHEN place = 'away'
THEN 1 END) away_matches,
count(CASE WHEN place = 'away' AND scored > conceided
THEN 1 END) away_wins,
count(CASE WHEN place = 'away' AND scored = conceided
THEN 1 END) away_draws,
count(CASE WHEN place = 'away' AND scored < conceided
THEN 1 END) away_lost,
SUM(CASE WHEN place = 'away'
THEN scored
ELSE 0 END) away_scored,
SUM(CASE WHEN place = 'away'
THEN conceided
ELSE 0 END) away_conceided,
GROUP_CONCAT((CASE
WHEN scored > conceided
THEN 'W'
WHEN scored = conceided
THEN 'D'
WHEN scored < conceided
THEN 'L'
END) ORDER BY date ASC separator '') streak
FROM
(
(SELECT
hm.date date,
hm.home_team_id team_id,
hm.score_home scored,
hm.score_away conceided,
'home' place
FROM matches hm
WHERE hm.season_id = :seasonId)
UNION ALL
(SELECT
am.date date,
am.away_team_id team_id,
am.score_away scored,
am.score_home conceided,

JOIN teams t ON t.id = team_id
