Description

I have a stats comparison sort function for stats using PHP's uasort. This works well with 2 teams however if more than 2 teams are tied, I need to be able to run a number of tie breaking rules. The function right now is:

function Compare_standings($ar1, $ar2){
if ($ar1['pts']<$ar2['pts']) {
return 1;
} elseif ($ar1['pts']>$ar2['pts']) {
return -1;
}
if (in_array($ar1['id'],$ar2['teamsbeat'])) {
return 1;
} elseif (in_array($ar2['id'],$ar1['teamsbeat'])) {
return -1;
}
if ($ar1['w']<$ar2['w']) {
return 1;
} else if ($ar1['w']>$ar2['w']) {
return -1;
}
if (($ar1['gf'] - $ar1['ga']) < ($ar2['gf'] - $ar2['ga'])) {
return 1;
} elseif (($ar1['gf'] - $ar1['ga']) > ($ar2['gf'] - $ar2['ga'])) {
return -1;
}
if ($ar1['ga'] == 0) {
$arg1 = 1;
} else {
$arg1 = $ar1['ga'];
}
if ($ar2['ga'] == 0) {
$arg2 = 1;
} else {
$arg2 = $ar2['ga'];
}
if (($ar1['gf'] + $ar1['ga']) / $arg1 > ($ar2['gf'] + $ar2['ga']) / $arg2) {
return 1;
} elseif (($ar1['gf'] + $ar1['ga']) / $arg1 < ($ar2['gf'] + $ar2['ga']) / $arg2) {
return -1;
}
return 0;
}

uasort($tstats['tm'], 'Compare_standings');

What I need to happen is add the ability to compare additional variables if 3 or more are tied. So say a team has the same amount of points as 2 other teams, it needs to go through a number of rules based on the 3 values, not just 2.
