PHP按值排序多个数组

Question

I want to know how can i sort this in PHP in base of "leaguePoints" and then in "wins"

<?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);

Im trying to port this from Java, wich i do in this way:

    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;
        }
    });
    }

Thank you very much for your time, i really appreciate your help.

I don't like to normally provide solutions, but you just needed to port it to another language.

Basically, you want to write a bubblesort callback, which will first compare two records wins properties, then if they are equal, fall back to the league points property. Something like

$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);
