Question

我想知道如何在PHP中基于＆＃34; leaguePoints ＆＃34;然后在＆＃34; 获胜＆＃34;

<?php
            foreach ($league as $leaguesList)
            {
                if ($leaguesList->queue == "RANKED_SOLO_5x5")
                {
                    foreach ($leaguesList as $list)
                    {
                       if ($list->division == $leagueSummoner->division){
                           $array[] = $list;
                       }
                    }
                }
            }

    var_dump($array);

结果： http://pastebin.com/QkKU7W0k

我试图用Java来解决这个问题，我是这样做的：

    public void setRankList(List<LeagueSummonerLeagueStats> _rankList) {

    rankList = _rankList;
    Collections.sort(rankList, new Comparator() {

        public int compare(Object match1Obj, Object match2Obj) {

            LeagueSummonerLeagueStats league1 = (LeagueSummonerLeagueStats) match1Obj;

            LeagueSummonerLeagueStats league2 = (LeagueSummonerLeagueStats) match2Obj;

            int i = Integer.compare(league2.getLeaguePoints(), league1.getLeaguePoints());

            if (i != 0)
                return i;

            i = Integer.compare(league2.getWins(), league1.getWins());

            if (i != 0)
                return i;

            return -1;
        }
    });
    }

非常感谢您的时间，非常感谢您的帮助。

Answer 1

你会想要usort()这样使用：

function myCompare($a, $b) {
    // comparison code here
}

usort($mydata, 'myCompare');

或使用匿名函数：

usort($mydata, function($a, $b){ /* ... */ });

或者您可以输入任何接受两个参数的Callable并返回负数，零或正数。

Answer 2

我不想通常提供解决方案，但您只需要将其移植到另一种语言。

基本上，你想写一个bubblesort回调，它首先会比较两个记录的胜利属性，然后如果它们相等，则回到联盟积分属性。像

这样的东西

$data = [
    [
        'wins' => 10,
        'leaguePoints' => 10,
    ],
    [
        'wins' => 10,
        'leaguePoints' => 20,
    ],
    [
        'wins' => 20,
        'leaguePoints' => 10,
    ],    
    [
        'wins' => 10,
        'leaguePoints' => 10,
    ],
];

usort($data, function($a, $b)
{
    if ($a['wins'] === $b['wins']) {
        if ($a['leaguePoints'] === $b['leaguePoints']) {
            return 0;
        }

        return ($a['leaguePoints'] > $b['leaguePoints']) ? -1 : 1;
    }

    return ($a['wins'] > $b['wins']) ? -1 : 1;
});

print_r($data);

Answer 3

不确定我的索引是否正确。

foreach($league as $leaguesList){

  foreach ($leaguesList as $key => $list){

    $leaguePoints = [$key] ["info"]["leaguePoints"];
    $wins = [$key] ["info"]["info"]["wins"];
    $sort = $leaguePoints *= 100 + $wins;
    $sorted[$sort] = $list;

  }
}
ksort($sorted);

PHP按值排序多个数组
