how to output a standings table on the fly from a mysql table of football [soccer] results?

Question

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.

// 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).
