【已解決】這個(gè)方法不會(huì)寫(xiě)啊，求高手相助

wocall

問(wèn)題描述

下面數(shù)組已經(jīng)按gross_total排名，rank為名次。

但是當(dāng)gross_total值相等時(shí)，名次也相等了，程序希望相同名次里也要排名，比如3個(gè)第三名，要排出3、4、5名來(lái)。

相同名次排名的數(shù)據(jù)從每個(gè)用戶的子數(shù)組scores中來(lái)比較，即先比較最后一條數(shù)據(jù)的gross，誰(shuí)的數(shù)值小，誰(shuí)就排前面；如果最后一行的gross也相等，那就倒數(shù)第二條，依此類(lèi)推，直到排出一個(gè)先后來(lái)。

要將數(shù)組里所有排名重復(fù)的用戶都要排出唯一的名次來(lái)，名次賦值給rank。

哪位大佬能幫我出出主意，如何寫(xiě)這個(gè)函數(shù)么？
或者有償服務(wù)也可。

不知道數(shù)據(jù)庫(kù)是如何設(shè)計(jì)的，但是可以將數(shù)據(jù)查出來(lái)之后，在代碼中排序就很簡(jiǎn)單了

可以自己實(shí)現(xiàn)排序算法，邏輯你已經(jīng)說(shuō)清楚了，關(guān)鍵就是進(jìn)行多次循環(huán)排序。
這里我推薦你使用 laravel的集合進(jìn)行排序，自定義一下排序字段就行如下

function grossSort(string|array $users)
{
    $gArr = is_array($users) ? $users : json_decode($users, true);
    $sortFn = ['gross_total'];
    $sortSubArr = $gArr[0]['scores'];
    krsort($sortSubArr);
    foreach ($sortSubArr as $k =>  $vArr) {
        $sortFn[] = fn (array $a, array $b) => $a['scores'][$k]['gross'] <=> $b['scores'][$k]['gross'];
    }
    $sorted  = (new \Illuminate\Support\Collection($gArr))->sortBy($sortFn)->values()->all();
    return $sorted;
}

    如果你的項(xiàng)目里面沒(méi)有 Illuminate\Support\Collection 可以使用 composer require -W illuminate/support 安裝

感謝樓上各位，受啟發(fā)，終于寫(xiě)出來(lái)了：

        usort($data, function ($a, $b) {
            if($a['gross_total'] == $b['gross_total']){
                for($i = count($a['scores'])-1; $i > 0; $i--){
                    if($a['scores'][$i]['gross'] == $a['scores'][$i]['gross']){
                        continue;
                    }else{
                        return $a['scores'][$i]['gross'] > $a['scores'][$i]['gross'] ? 1 : -1;
                    }
                }
            }else{
                return $a['gross_total'] > $b['gross_total'] ? 1 : -1;
            }
        });
