Как выводить таблицу позиций на лету из таблицы mysql результатов футбола [футбол]?

Ответ 1

Сначала соедините таблицу баллов, заменяя hometeam с awayteam и заменяя счет цели. Это дает вам некоторые исходные данные, которые легко агрегируются, и запрос на создание карточки счета выглядит примерно так:

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 ;
}

ПРИМЕЧАНИЯ. Я не тестировал его и все, может быть, небольшая ошибка (некоторые $ или ; отсутствуют).

Недавно мне пришлось сделать более расширенную версию данных. Хотя он основан на моей собственной схеме, но он может быть полезен для кого-то (он основан на предыдущем ответе a'r):

  SELECT
    team_id                                             team_id,

    t.country                                           country,

      THEN 1 END)                                       wins,
    count(CASE WHEN scored = conceided
